Searching WorldCat Indexes

Last revised: October 2013

1 Scope

Purpose

This guide provides comprehensive information about indexes used to retrieve records from WorldCat. OCLC services, including cataloging, reference, and resource sharing, use the same search indexes. Interfaces for searching WorldCat include:

  • OCLC Connexion® client and browser (cataloging)
  • OCLC CatExpress® in Connexion browser (copy cataloging)
  • OCLC FirstSearch® (reference)
  • OCLC WorldShare™ (Acquisitions, Circulation, Interlibrary Loan, Metadata)
  • OCLC WorldCat Resource Sharing (interlibrary loan)

This guide shows MARC fields and subfields indexed for each WorldCat index, gives examples, and provides information about how each index works to help construct searches that retrieve the records you need.

Please note: Connexion and FirstSearch support the following non-Latin/non-roman scripts: Arabic, Armenian, Bengali, Chinese, Cyrillic, Devanagari, Ethiopic, Greek, Hebrew, Japanese, Korean, Syriac, Tamil, and Thai. Many WorldCat indexes support both Latin script and non-Latin script search terms. In WorldCat index descriptions, each description notes whether that index supports non-Latin script search terms.

Who should use this guide?

This guide is for library staff who use the OCLC interfaces listed above to search WorldCat.

It is not meant for end-user patrons of libraries who have public access to WorldCat through FirstSearch or Resource Sharing.

Neither is this guide for users of OCLC Z39.50 access to cataloging and to FirstSearch. Those who use Z39.50 configure their own search indexes when they configure their individual local Z39.50 client. See information at:

Levels of searching and examples in this guide

To give flexibility in search strategy and control over the results, OCLC search interfaces provide various levels of searching, from simplified to complex.

The most complex search level requires knowledge of full search syntax–all parts of a search in correct order and format, including index labels and punctuation, search terms, Boolean operators, and qualifiers.

Examples of complex search levels: An "expert" search in FirstSearch or a "command line" search in Connexion.

Interfaces also provide less complex levels of searching where you use text boxes and drop-down lists to enter or select the parts of the search. The interface automatically formulates the correct search syntax when you send the search to the OCLC system.

Examples of less complex search levels: A "basic" search in FirstSearch/Resource Sharing or CatExpress or a "guided" search in Connexion.

Note: Not all indexes are listed in drop-down lists in searching interfaces. If an index is not a selection in a drop-down list:

  • In Connexion, you must enter a full syntax "command line" search that includes the index label, punctuation, and search term for the index.
  • In FirstSearch and WorldCat Resource Sharing, you can enter a search term preceded by the index label and punctuation in any search box; the index you type overrides the index selected in the drop-down list adjacent to the search box.

Examples of searches in this guide are given in full search syntax (most complex format). From full syntax examples, you can extrapolate the parts of a search you would enter or select in boxes and lists to construct a basic or guided form of the search.

Caution. Although constructed as "real" WorldCat searches that produce actual results, the examples in this guide can only illustrate the principles of searching. Over time, results of running a search example may change. Because of the dynamic nature of WorldCat, search examples used here may no longer retrieve records or may retrieve too many records.

About the index descriptions

Each WorldCat index is described in alphabetical order in a separate table in this section. Some indexes include word, phrase (complete subfield), or whole phrase (complete field) versions, or a combination of these. See Types of searches for a detailed explanation of word, phrase, and whole phrase indexing.

Note: Most whole phrase indexes are available only in Connexion. The only whole phrase index available in FirstSearch and Resource Sharing is the Subject heading index (use index label sa=).

For various views of the scope of WorldCat indexing, see also List of fields and subfields indexed in tag order and Search index check lists.

Each index description in this section has the following information:

Column Information shown
Search by  Type of data to enter in a search of the index, including:
  • Word, phrase (complete subfield), or whole phrase (complete field).
  • Number or number phrase.
  • Derived segments of words.
  • Specific codes or symbols.
See Types of searches for more information.
Label  The index labels and punctuation.
Fields and subfields indexed  Fields and subfields the system searches to match the search term.
Guidelines and examples 
  • Notes the indexes you can browse as well as search
  • Notes the indexes that support non-Latin script search terms
  • Gives any special guidelines specific to the index.
  • Provides search examples shown in full search syntax.
  • Notes indexes that have additional fields/subfields to cover bibliographic institution records (IRs), with a URL to a list of the IR fields/subfields added.

Notes:

  • Asterisks next to index names. Asterisks indicate qualifier indexes used mainly to limit search terms.
  • LC acronym. LC = Library of Congress throughout. The OCLC symbol for LC is DLC.

Non-Latin/non-roman scripts in searches

The Connexion client and FirstSearch interfaces support non-Latin script search terms. The many WorldCat indexes that support both Latin script and non-Latin script searching are noted in the individual descriptions. The following scripts are supported: Arabic, Armenian, Bengali, Chinese, Cyrillic, Devanagari, Ethiopic, Greek, Hebrew, Japanese, Korean, Syriac, Tamil, and Thai.

Qualifier indexes

In Connexion only, some values and codes for qualifying searches can be entered by simply preceding with a slash instead of an index label and colon ( :) or equal sign ( =). Slash qualifiers are available in FirstSearch WorldCat or WorldCat Resource Sharing for derived searches only. Do not use slash qualifiers in WorldShare.

Keyword search examples in this section that include qualifiers are shown with index labels only, so that they illustrate WorldCat searching in all interfaces.

See Combine, qualify, expand searches for details and examples of using slash qualifiers in Connexion.

Indexing for bibliographic institution records (IRs)

About IRs. Institution records are contributed by individual libraries whose authorizations include IRs. They are intended to preserve local library notes, locations, and other data which may be of general interest. They are attached to WorldCat master records.

Indexing for IRs. Additional fields/subfields have been added to existing WorldCat indexes that retrieve master records with attached IRs based on unique data in the IRs.

Three new indexes cover IRs only:

  • General call number ( nu: or nu=)
  • IR control number ( ir:)
  • System control number ( sy:)

IR fields and subfields indexed. The new IR-specific indexes and additional fields/subfields for IRs are not described or included in this document. See IR indexing details.

Retrieving IRs in Connexion. You must set an option to include IR indexes in WorldCat searches (for example, in Connexion client, click Cataloging > Search > WorldCat and then click Settings). WorldCat search results include only the master records to which IRs are attached. You can display attached IR(s) from a master record.

When the IR index option is set, your search includes the fields and subfields of both master records and attached IRs for the index you specify. However, the search retrieves only WorldCat master records with data that matches the search and any master records that have IRs with unique data that matches the search. You cannot retrieve IRs directly from a WorldCat search, but you can display them from a master record. To view IRs attached to retrieved master records in Connexion client:

  With a WorldCat record displayed that has IRs attached, click Cataloging > Show and then click one of the following:
  • All Institution Records
  • My Institution Records
  • Institution Records for [enter the OCLC symbol for a library whose IRs you want to view]

If you are authorized to work with IRs, you can create and add, edit and replace, or delete your own institution records only. However, anyone can copy and paste, export, or print IRs. Also, anyone can view IRs attached to retrieved master records without setting the option to include IR indexes in WorldCat searches.

Retrieving IRs in FirstSearch. You can retrieve and view IRs only if your authorization has been set for IRs using the FirstSearch administration module. To view IRs:

  When you have the IR search option selected in your FirstSearch module, WorldCat records that have attached IRs display a More Records label with a Show record information link. Click the link to see attached IRs.

3 List of fields and subfields indexed in tag order

The table in this section lists all fields and subfields indexed and shows the indexes that include them. Word, phrase (entire subfield) and whole phrase (entire field) versions of indexes are distinguished by whether the two-letter index label is followed by a colon (:), or by an equal sign (=), or by a letter "w" and an equal sign, respectively. See Types of searches for a detailed explanation of word, phrase, and whole phrase indexes.

Note: Whole phrase indexes are available only in Connexion. FirstSearch and Resource Sharing have only one whole phrase index—the Subject heading index ( sa=).

The fields and subfield groupings are listed in numerical tag order and within a tag group, in alphabetical order by index name. Click a link in the table to see the detailed description of an index.

Key to abbreviations:

Conx = OCLC Connexion

FS/RS = OCLC FirstSearch and Resource Sharing

LC = Library of Congress

LCSH = Library of Congress subject heading

MeSH = Medical subject heading

NAL = National Agricultural Library

NLM = National Library of Medicine

5 Types of searches

Basic guidelines

  • Index labels and punctuation required. Always use index labels followed by correct punctuation and then the search term–for example, kw:politics–unless you are selecting indexes from a list.
    Exceptions:
    • In a Connexion command line search and in a FirstSearch WorldCat and WorldCat Research Sharing expert search, index labels are not required for the following searches if they are the first or only element of a full syntax search:
      • Derived searches
      • ISBN search
      • OCLC number search preceded by an asterisk ( *) or number sign ( #)
    • In WorldShare, the index label is not required for:
      • ISBN searches
      • ISSN searches
      • Government document number
  • Keyword index is the default. If you do not include an index label, the system uses the keyword index ( kw:) as the default. See a description of the keyword index in "WorldCat index descriptions."
  • Spacing.
    • In Connexion, do not enter spaces between the index label and punctuation or between punctuation and the search term. Example: kw:software.
    • In FirstSearch WorldCat searches, close up spaces or leave a space between punctuation and the search term. Example: kw:software or
      kw: software.
  • Case. Index labels and search terms can be upper- or lowercase or a combination.
  • Stopwords. The system ignores common words in some types of searches. You can omit them from search terms. See a list of stopwords for keyword searches and a list for derived name searches in sections below that cover these search types.
  • Non-Latin scripts in searches. Use any supported non-Latin script for WorldCat searches in the Connexion client or FirstSearch interfaces. Currently supported non-Latin scripts include: Arabic, Armenian, Bengali, Chinese, Cyrillic, Devanagari, Ethiopic, Greek, Hebrew, Japanese, Korean, Syriac, Tamil, and Thai scripts.

Treatment of initial articles in searches

Omit initial articles in the following types of searches:

  • Beginning of these searches:
    • Derived title
    • Derived corporate name
    • Title word and phrase browsing (index scanning)
  • Keyword searches: stopwords are not indexed. (See list of keyword stopwords later in this section.)
  • Title phrase ( ti=) searches: The system automatically ignores English articles a, an, and the.

See a comprehensive list of initial articles on the Library of Congress Web site.

Notes:

  • If a word listed as an initial article on the LC Web page is the first word of a search but has a different meaning (for example, ein or un used to mean one, or thé used to mean tea), include the word in a search.
  • In cataloging, a second indicator of 1 or higher in a field indicates how many initial character spaces to ignore for indexing, filing, and sorting.

Word, phrase, or whole phrase searches

Many WorldCat keyword and numeric indexes are searchable and browsable separately by words, phrases, and whole phrases. Index labels and punctuation distinguish whether you want to find a word, phrase, or whole phrase in an index, as shown in the following table:

Search by ... Format of index label System finds Example
Word xx:  Word or number anywhere in indexed field Publisher:
pb:dakota
Dewey Class Number: dd:616
LC Class Number: lc:z5074.g8 
Phrase xx=  Complete data in indexed subfield Personal name phrase: pn=james, henry
Publisher phrase: pb=namgyal institute of tibetology 
Whole phrase
Note: Only one whole phrase index (Subject All sa=) is available in expert FirstSearch WorldCat and WorldCat Resource Sharing searching.
xxw=
FirstSearch WorldCat and WorldCat Resource Sharing indexes do not include w.
Complete data in indexed field, across all indexed subfields Connexion only:
Personal name whole phrase: pnw=james, henry 1843-1916
Connexion subject whole phrase: suw=library science computer network resources
FirstSearch WorldCat and WorldCat Resource Sharing subject whole phrase: sa=library science computer network resources 

Note: Use the same index labels and punctuation for browsing.

  • In a Connexion command line search, precede with the Scan command ( sca) and a space.
    Example:
    sca ti:buddenbrooks
  • In the FirstSearch WorldCat and WorldCat Resource Sharing expert search screen, click the browse button,
    , and use the browse screen to enter a full syntax browse (do not enter Scan command).
    Example:
    ti:buddenbrooks

Guidelines for word, phrase, and whole phrase searches

Word indexes:

  • Enter multiple words in a string (do not separate with Boolean and) to find any instance of any term in a single index.
    Example:
    ti:asian crisis
  • Enclose more than one word in quotation marks to find the exact sequence of the words.
    Example:
    ti:"asian crisis"
  • Combine words with proximity operators with ( w) or near ( n) and an optional number (1 to 25) to find the exact sequence of the words or the sequence with no more than the specified number of words between. (See Combine, qualify, expand searches for more details.)
    Example:
    ti:asian w2 crisis

Phrase indexes:

  • Include all subfield data, or truncate using the asterisk ( *).
    Example: pb=namgyal institute*
    Alternative: Browse for the phrase: [ sca ] pb=namgyal institute
    Use the scan ( sca) command in a Connexion command line search; in FirstSearch and Resource Sharing, you must use the browse button, , to enter a browse term). Browsing automatically truncates phrases. (See Combine, qualify, expand searches for more details.)
  • Retain periods in classification numbers.
  • Omit initial articles in titles.
  • Retain the first comma for personal name indexes if it is not the last element in the subfield.
  • Retain hyphens in dates.
  • Omit other punctuation.

Whole phrase indexes:

  • Most whole phrase (or mapped phrase) indexes are not available for searching WorldCat in WorldShare, FirstSearch, Resource Sharing, except for the Subject whole phrase index (index label sa=) which is same as Connexion Subject whole phrase index (label suw=).
  • Enter all field data, or truncate using an asterisk ( *).
    Example: suw=library science computer* (Connexion)
    Example: sa=library science computer*
    (FirstSearch and Resource Sharing)
    Alternative: Browse for the whole phrase: In Connexion, enter sca suw=library science computer. Use the Scan ( sca) command in Connexion only. In FirstSearch WorldCat and WorldCat Resource Sharing, click the Browse icon, and enter sa=library science computer. Browsing automatically truncates a phrase.
  • Omit initial articles in titles.
  • Retain the first comma for personal name indexes if it is not the last element in the subfield.
  • Retain hyphens in dates.
  • Include parentheses when present in a whole phrase search term, but enclose the entire search term in quotation marks ( ") so that the system does not interpret the parentheses as a nested search.
  • Combine word, phrase, or whole phrase searches in more than one index with Boolean operators. (See Combine, qualify, expand searches for more details.)

Numeric searches

Searching for numbers–accession numbers, such as the OCLC control number or LCCN; standard numbers, such as an ISBN or ISSN; or a class number, such as a Dewey or Library of Congress classification number–is one of the most efficient ways to search.

A number search can retrieve a single record (for example, by its unique ISBN) or precisely related records (for example, by class number). Numbers are usually unique to a single record or group of related records.

A number search is simply entering a number as a keyword. Follow these general guidelines to search for significant numbers in records:

  • Type all numbers and letters.
    Tip for entering ISBNs ending in x:
    If you use the number keypad, truncate the number using the asterisk key ( *).
  • Omit spaces.
  • Omit punctuation, except keep periods ( .) in classification numbers.

Keyword searches

A keyword is any word that is part of a record's bibliographic information and is significant or descriptive enough to retrieve the record(s) you need.

A word is any character(s) between two blank spaces:

  • Initials and abbreviations are words.
  • Words with characters attached by punctuation marks, such as an apostrophe, are not yet normalized in the system (that is, they are not indexed together so that a search term with or without the character retrieves the same records).
    For now, you can enter both forms combined with OR to retrieve all appropriate records.

    Example: To search the title index for l'étranger, type ti:etranger or letranger.

  • For hyphenated words:
    • In Connexion: Substitute a space for the hyphen (system treats as two words). If searching a word index rather than a phrase index, enclose the two parts of the hyphenated word in quotation marks to find the words together in sequence.
    • In FirstSearch WorldCat and WorldCat Resource Sharing: You can either enter the hyphen or substitute a space. The system searches for the two words next to each other.
  • Keywords can be combined in searches. Type a string of words to search a single index for any instance of the words in indexed fields (enclose words in quotation marks to find the words together in exact sequence) or combine with Boolean operators ( and, or, not) to search multiple indexes.

    Examples:
    ti:asian crisis
    ti:asian and su:crisis

Stopwords for keyword searches

The system ignores the following common words in a keyword search statement:

a but he it so to you
an by her its than was  
and for his not that were  
are from if of the when  
as had in on their which  
at has into or there with  
be have is she this would  

To use any of these words as search terms, enclose them in quotation marks.

Example: To search for the title And Then There Were None, which includes three stopwords, type ti:"and" then "there" "were" none.

Derived searches

This feature is not available in WorldShare.

Derived searching reduces the number of keystrokes you enter.

A derived search uses a specific number of initial characters from sequential words in a name or title.

  • The "derived" segments of the words are separated by commas.
  • A word is defined the same as for keyword searching (any character(s) between two blank spaces).
  • The number and pattern of letters and commas tells the system which derived index to search.
  • In a Connexion command line search or a FirstSearch/Resource Sharing expert search, using the derived search index label and punctuation is optional if it is the first or only element of the search.
    Always use index labels and punctuation when combining a derived search with a search in a different index.

The following table describes the four types of derived searches:

Index Index label Number of initial letters and commas Minimum key (see general notes) Index-specific notes
Title td:  3,2,2,1 None Cannot use circumflex.
Personal name pd:  4,3,1 4,1,blank  
Corporate/conference name cd:  =4,3,1 4,1,blank Leading equal sign (=) distinguishes this index from personal name index if you enter without a label.
Name/Title nd:  4,4 4,4 For records without 1xx fields, minimum key can be blank,4.
General notes:
  • Minimum key. The minimum key pattern shows how few letters you can type and still retrieve all possible characters up to the required number of letters. For example, both pd:moza,wol, and pd:moza,wol,a retrieve records for Mozart, Wolfgang Amadeus.
  • Use of circumflex. Use a circumflex ( ^) in any derived search except a title search to exclude a character from its position in the search. For example, to search for the name Harvey, Henry, which consists of only two parts, type harv,hen,^

Follow these general guidelines for constructing derived searches:

  • Even if a name or title has fewer words than the derived search sequence calls for, type all commas. Example:
    To search for the title Roots, type td:roo,,,.
  • Omit initial articles "a," "an," and "the" and their non-English equivalents from title searches or segments, but include if they appear anywhere else in titles. (See initial articles listed on the Library of Congress Web site.)
  • Include letters and numbers.
  • Exclude non-alphabetic and non-numeric characters.
  • Exclude punctuation and diacritics.
  • If a personal name begins with Mc or Mac followed by an uppercase letter, type m and omit c or ac; if followed by a lowercase letter, include c or ac
    Example: To search for MacDonald, Marion B., type pd:mdon,mar,b. To search for Macdonald, Andrew T., type pd:macd,and,t.
  • For constructing segments of a personal name search:
    • Use the first four characters of the surname, the first three characters of the forename, and optionally, the first character of the middle name, separated by commas.
    • The surname includes all words that appear before the first comma.
    • Compound or hyphenated surnames: When constructing a derived name search or name segment, treat all parts of a name up to the first comma as the first element of the derived search, whether they are separated by a space or a hyphen.
      Examples:
      Type pd:vanh,car,j to find Van Huell, Carolus Johannes .
      Type pd:lima,moy, to find Li-Marcus, Moying .
    • Forename only: If the comma is the last element of the subfield, or if there is no surname, treat each part of a name as separate segments. Treat a hyphenated name as two separate parts.
      Examples:
      Type pd:whit,bul, to find White Bul l.
      Type pd:li,min,t to find Li- Min Tau .
      Type pd:henr,vii,k to find Henry VIII, King of England .
  • For constructing a derived title search or title segment for hyphenated words, treat the words as separate.
    Example: Type td:asy,di,va,i to find Asymmetrically- distributed variations in traveler-perceived travel times....
  • Do not construct derived searches using non-Latin script data.

Stopwords for derived name searches

Omit the following words as the first segment only from a corporate/conference name and from the name portion of a name/title search.

& Congress International North Carolina Texas
a Connecticut Iowa North Dakota the
Alabama Council Joint of U.N.
Alaska Delaware Kansas Office U. N.
American Department Kentucky Ohio United Nations
an Dept. Louisiana Oklahoma United States
and Division Maine on University
Arizona East Maryland Oregon U.S.

Canada House National Society Wisconsin
College Idaho Nebraska South Workshop
Colloquium Illinois Nevada South Carolina Wyoming
Colorado in New Hampshire South Dakota  
Commission India New Jersey State  
Committee Indiana New Mexico Subcommittee  
Commonwealth Institute New York Symposium  
Conference International North Tennessee  

Examples:

Omit initial stopwords in search for... Enter search as...
Corporate author Great Britain Forestry Commission of map(s) published in 1985 cd:fore,com,/1985 
Corporate author United Nations Committee on Economic, Social and Cultural Rights   cd:econ,soc,a 
Corporate name Indiana Supreme Court and title Race and gender fairness   nd:supr,race 

Browsing

Browsing scans an index with the intent of finding a matched term or the closest matching term, rather than retrieving records. Selecting a term in a browse results list then retrieves the relevant record(s).

Each index description in "WorldCat index descriptions" notes whether the index supports searching only or both searching and browsing.

Browse WorldCat using:

  • A word that appears anywhere in indexed fields and subfields.
    Or
  • An exact phrase (complete subfield) or whole phrase (complete field), starting with the first word and including all words (but excluding initial articles in titles). The phrase you enter is matched character by character, from left to right, against the characters of the phrase in the index you specify.
    The system returns a list of terms showing a match or the closest match, along with terms that precede and follow the matching term. When you open an entry on the list, you see the record or a list of records retrieved for that term.

Follow these general guidelines for browsing:

  • Include up to 60 letters, numbers, spaces, or these characters: ( ) &
  • Omit initial articles and non-English equivalents from titles ( as listed on the Library of Congress Web site).
  • Include hyphens or substitute a space (system treats as two words).

    Example:
    sca td:asymmetrically distributed finds both titles, Asymmetrically-distributed variations... and Asymmetrically distributed information....

  • Do not use qualifiers, wildcards, or combined terms for browsing.

Tips for browsing

  • Truncation. Browsing provides automatic truncation without using the truncation symbol. Type only as many characters or words as needed.
    Example: To browse for the title Let Us Now Praise Famous Men, type tiw=let us now praise famous
  • Browse for titles.
    • Use the title phrase index ( ti=) to browse for title/subtitle combinations. The title browse index includes 245 ‡b.
    • In Connexion: Use the title whole phrase index ( tiw=) to browse for a title proper (cataloger-constructed title access point). The index excludes 245 ‡b.
    • In FirstSearch WorldCat and WorldCat Resource Sharing: Use the Subject All index ( sa=) in expert searches. Subject All is the only whole phrase index available in FirstSearch/Resource Sharing.

6 Combine, qualify, expand searches

Combine searches

Use the Boolean operators shown in the following table for combining search terms to narrow or broaden searches:

Boolean operator What the operator does Example Notes
and  Finds all terms anywhere in a record. su:wom?n and ti:history and gc:new york and yr:1970-  For WorldShare, Boolean operators must be in all uppercase letters (AND, OR, NOT)
or  Finds any single term or all terms. pn=woolf, virginia or pn=woolf, leonard and yr:1900-50 
not  Excludes the term that follows not. ti=civil war not su:battle not gc=united states 

Use the following proximity operators to indicate relationship and, optionally, position of search terms in relation to each other:

Proximity operators What the operator does Example
with
(or w)
Finds both terms, in the order typed, with no words between. ti:aluminum w wiring
Alternate:

Enclose phrase in quotation marks: ti:"aluminum wiring" 
Followed by a number (1 to 25), finds both terms, in the order typed, with no more than the specified number of words between. ti:aluminum w2 wiring 
near
(or n)
Finds both terms, in any order, with no words between. ti:moon n eclipse 
Followed by a number (1 to 25), finds both terms, in any order, with no more than the specified number of words between. ti:chicken n3 egg 

Nesting. Boolean searches can be nested using parentheses.

  Example:
ut: (civil w1 war) and (battlefield w1 command*) 

Include an operator as a keyword in a search. To use and, or, not, with, or near as part of a search statement, enclose it in quotation marks to prevent the system from treating it as an operator.

  Example:
To search for the title Neighbors Near and Far which includes near and and, normally treated as operators, type ti:neighbors "near" "and" far.

Guidelines for combining searches

  • Type operators between search terms to combine them.
  • In WorldShare, Boolean operators must be in uppercase letters (AND, OR, NOT)
  • Do not use Boolean or proximity operators and, or, not, with, or near for browsing (scanning indexes).
  • Do not use proximity operators with or near for derived searches.
  • Do not truncate a music publisher number or government document number in a combined search; type the complete number.
  • In WorldShare, do not use the near or with proximity operators.

Qualify searches

Qualifying a search is combining numeric, keyword, or derived search terms with qualifier indexes and supported values using Boolean operators and or not.
Examples:
su:scotland and mt:map and yr:2000-
cn:microsoft and yr:2003 not mt:url

Qualify searches to make them more precise and narrow your results. Each qualifier index listed below is described in detail in "WorldCat.index descriptions."

Although in the Connexion command line or in the FirstSearch/Resource Sharing expert search, you can search using the following "qualifier" indexes alone, but alone they are likely to retrieve too many records. Qualifier indexes are meant to be combined with other indexes to limit a search by a specific attribute.

  • Material type: Limits a search to one of over 100 specific material types (see the list in WorldCat index descriptions or see the table of indexed values in Format and material type values indexed).
  • Years of publication: Limits a search to a year or range of years.
  • Microform or not microform: Limits a search to microforms or excludes microforms.
  • Cooperative programs: Limits a search to records produced by the Library of Congress (LC) or LC cooperative programs.
  • Internet or not internet: Limits a search to Internet resources or excludes Internet resources.
  • Language: Limits a search to items in a specific language.
  • Holding library: Limits a search to items held by a specific library.

Guidelines for qualifying searches

  • Qualifiers can appear in any order in a search.
  • In Connexion searches and for FirstSearch/Resource Sharing derived searches only: The following qualifiers can either be entered with an index label and colon or appended to a search with slashes:
    • Format/Document type
      Examples:
      cn:microsoft and mt:vis or cn:microsoft/vis (Connexion)
      =harv,uni,/map or cd:harv,uni, and mt:map (Connexion, FirstSearch, Resource Sharing)
    • Year
      Examples:
      tiw=myth of sisyphus/1955 or tiw=myth of sisyphus and yr:1955 (Connexion)
      myt,of,si,/1955 or td:myt,of,s, and yr:1955 (Connexion, FirstSearch, Resource Sharing)
    • Microform
      Example:
      cn:microsoft and mf:mic or cn:microsoft/mic (Connexion)
    • Cooperative programs (cataloging source)
      Examples:
      ti:paper airplanes/dlc (Connexion)
      ti:paper airplanes and dl:y or td:pap,ai,,/dlc (Connexion, FirstSearch, Resource Sharing)
  • To use slash qualifiers with derived searches in FirstSearch/Resource Sharing expert searches, the derived search must be the first or only element of a search.
  • If you use slash qualifiers:
    • Type as the last element(s) of a search.
    • Use only one of each type listed above, in any order.
      Example:
      ovid,meta/bks/dlc/1600-99
  • You cannot qualify browse terms.

Expand or focus searches using wildcards and truncation

Use the following wildcard and truncation symbols to expand or focus searches:

Symbol Function How to use Example
#
(number sign)
Wildcard Replace one character in a search. wom#n retrieves woman and women 
?
(question mark)
Or
?n (question mark followed by a number from 1 to 9)
Wildcard Replace any number of unknown characters.

Or

Followed by a number, replace the specified number of unknown characters.
encyclop?dia retrieves encyclopedia and encyclopaedia
re?4tion retrieves recreation, refraction, relaxation, etc.
*
(asterisk)
Truncation Add to the end of a word to retrieve variant endings. connect* retrieves connect, connection, connectivity, etc.

Result: The system retrieves up to 300 matches to search terms when you use wildcards or truncation.

Guidelines for using truncation and wildcard symbols

  • Precede a truncation or wildcard symbol by at least three characters.
  • For non-Latin script search terms in Connexion client and FirstSearch/Resource Sharing, truncation can be used for Bengali, CJK (Chinese, Japanese, and Korean), Devanagari, Tamil, and Thai scripts only. For other supported non-Latin scripts, use browsing for automatically truncation.

Examples of qualified searches

Each search in the following table is shown as both a keyword/numeric search and a derived search.

7 Treatment of special characters in Latin script searches

The following table of punctuation, diacritics, and special characters describes how to treat each character when you construct WorldCat search or browse terms. The characters listed are in the MARC-8 Latin script character set approved for MARC 21 cataloging.

Note on searches for non-Latin script data: The Connexion client supports using non-Latin script character sets for cataloging activities, including searching WorldCat. FirstSearch also supports non-Latin/non-roman script WorldCat searches. Non-Latin scripts currently supported include Arabic, Armenian, Bengali, Chinese, Cyrillic, Devanagari, Ethiopic, Greek, Hebrew, Japanese, Korean, Syriac, Tamil, and Thai scripts.

Name Character How to treat in search and browse terms

æ or Æ

æ or Æ Substitute the letters ae.
Acute ´ Omit and close up the space.
Alif/modifier letter right half ring Alif diacritic mark  Omit and close up the space.
Almost equal to Omit and leave a space.

Ampersand

& Type.
Apostrophe '
  • Omit and close up the space.
  • Omit from word searches. Words preceded by single letter c, d, j, l, m, n, s, or t and an apostrophe are not yet normalized in the system (that is, not indexed together so that a search term with or without the character retrieves the same records). For now, enter both forms combined with OR to retrieve all appropriate records. For example, to search for l'etranger, enter etranger or letranger.
  • Omit from Dewey class number searches; however, if Dewey class numbers contain slashes, the system indexes them both with and without data following the slashes. For example, 123.45/67/89 is indexed as 123.45 and 123.4567 and 123.456789.
Asterisk * Omit and leave a space.
At sign @ Omit and leave a space.
Ayn Ayn diacritic mark  Omit and close up the space.
Backslash \
  • Omit and leave a space.
  • Type in an access method phrase search. (See a description of the access method index in chapter 3.)
Brackets and bracketed information [ ] Omit and close up the space.
  • Omit opening and closing brackets and close up the space.
  • Omit brackets and data within the brackets in these two cases:
    • [sic]
    • [i.e. and any following data ]
  • Otherwise, include data within brackets in searches.
Breve ˘  Omit and close up the space.
British pound £ Omit and leave a space.
Candrabindu Candrabindu diacritic  Omit and close up the space.
Cedilla ¸ Omit and close up the space.
Circle above letter (angstrom) Circle above diacritic  Omit and close up the space.
Circle below letter ̥ Omit and close up the space.
Circumflex, spacing or nonspacing ^
  • Omit and close up the space, except include spacing circumflex in URLs.
  • Add to some types of derived searches for greater precision. (See chapter 2 for more about derived searching.)
Colon : Omit and leave a space.
Combining double grave accent   Omit and close up the space.
Combining retroflex hook below   Omit and close up the space.
Combining inverted breve below   Omit and close up the space.
Combining macron below   Omit and close up the space.
Comma , 
  • Omit and leave a space.

8 Format and Material type values indexed

About the tables

The first two tables in this section show values and other criteria indexed for each Format/Document type index (first table) and for each Material type index (second table).

For searching: To limit a search by a Format or by a Material type, enter the index label and a colon ( mt:) followed by:

  • The code shown in column 1 of the tables
    Or
  • The name shown in column 2 of the tables
    Exception: Slash qualifiers. In Connexion searches or in derived searches only in FirstSearch/Resource Sharing expert searches (if the derived search is the first or only element of the search), you can precede most primary Format/Document types with either a slash or the index label and colon, as shown in the first table.
    Example: nd:mann,budd and mt:bks or nd:mann,budd/bks

Notes on RDA content, media, and carrier type terms and codes:

The tables at the end of this section, following the main two tables, show RDA content, media, and carrier type terms and codes that may occur in fields 336, 337, and 338 of records (term in ‡a; corresponding code in ‡b). Most of these terms and codes are indexed in OCLC Format and Material type indexes. A record can have either a term or a code to be indexed. The RDA tables list the material type index(es) that cover each RDA term/code. (RDA = Resource Description and Access, the proposed successor to AACR2.)

In addition, a note is added in the "Other criteria" column of the main tables for each OCLC Format or Material index that covers an RDA term/code. The notes link to the RDA tables..

To retrieve records with an RDA term or code, limit a search by a Format or Material type index that covers it.

How to read the Format/Document type and Material type tables:

  • The first table shows indexed values for primary Format/Document type indexes.
  • The second table shows values for Material type indexes (narrower subcategories). Both lists are alphabetized by Format and Material type name.
  • Columns in the tables show values and/or criteria indexed two ways:
    • Based on the Leader, 007, 008, and other criteria
      And
    • Based on 006 fields
  • Each row shows separate sets of values indexed for each format or material type. Each format or material type may have up to six possible sets of values.
  • Values shown are in byte position 0 (first position), or if values are in another byte position, the position is shown following a slash:
    Example: 008/23=s (the value s is in byte 23 of the 008). For element labels see Bibliographic Formats and Standards or OCLC-MARC Records.
