batch processing in Connexion client
In Connexion client, the process of sending and completing a group of searches for bibliographic and/or authority records and/or a group of final actions in WorldCat all at once. Using client local files (files stored on the Connexion client cataloger's workstation), the cataloger enters search strings and/or marks saved records for actions and then initiates batch processing. The client automatically logs on to the system, runs the WorldCat searches and/or processes record actions, and produces reports, accessible in the client, for the results.

batch processing limits in Connexion client
None. Batch processing is limited only by the size of your hard drive. Note: Local files used for batch processing are limited to storing no more than 9,999 records. However, Connexion users can run as many local files as you want in a single batch.

A process by which records to be processed are collected into batches. The records in a batch are loaded all at once. See OCLC Batchloading services.

Bibliographic Formats and Standards
Guide to machine-readable cataloging records in WorldCat. This guide provides tagging conventions, input standards and guidelines for entering information into WorldCat. (Available on the OCLC Web site at

See Books format.

Books format
OCLC-MARC format used for cataloging books and book-like material. In WorldCat searches, use the Books index (label: bks) as a qualifier to limit results to records for this type of material.

Boolean operators
AND, OR, and NOT. Used to combine search terms. AND finds only records that contain both terms. OR finds records that contain either term. NOT finds records that contain the first term but not the second term. Combining search terms produces more precise and manageable search results.

Boolean logic (searches)
A system of logical thought developed by English mathematician George Boole (1815-64). A Boolean search combines key concepts or search terms with the logic operators AND, OR and NOT to specify the exact information required in a database search.

brief list
In Connexion, default display of WorldCat search results when a search retrieves 2 to 5 records. Each entry presents selected bibliographic data.

Scan an index for a match or the closest match to a term (word, phrase, or whole phrase) in records. The system matches the exact text string—character by character, from left to right—against the characters in the specified index. Produces a browse list that highlights the closest match and shows the number of records for each term in the list. Clicking an entry opens the record or a record list, if multiple records match.

Machine-Readable Cataloging. An international standard digital format for the description of bibliographic items developed by the Library of Congress during the 1960s to facilitate the creation and dissemination of computerized cataloging from library to library within the same country and between countries. By 1971, the MARC format had become the national standard for dissemination of bibliographic data and by 1973, an international standard.

Several versions of MARC are in use internationally, the most predominant of which is MARC 21, created in 1999 as a result of the harmonization of U.S. and Canadian MARC formats. UKMARC is used primarily in the United Kingdom. UNIMARC is widely used in Europe. Besides formats for bibliographic records, the MARC 21 family of standards now also includes formats for authority records, holdings records, classification schedules, and community information.

See Medical Subject Headings.

Literally, "data about data." Structured information describing information resources/objects for a variety of purposes. Although AACR2/MARC cataloging is formally metadata, the term is generally used in the library community for non-traditional schemes such as the Dublin Core Metadata Element Set, the VRA Core Categories, and the Encoded Archival Description (EAD). Metadata has been categorized as descriptive, structural, and administrative. Descriptive metadata facilitates indexing, discovery, identification, and selection. Structural metadata describes the internal structure of complex information resources. Administrative metadata aids in the management of resources and may include rights management metadata, preservation metadata, and technical metadata describing the physical.

OCLC cataloging
OCLC's online services for cataloging library materials using WorldCat and for producing machine-readable records and other offline products. Participating institutions retrieve bibliographic records, modify the information for local use, and then order the modified record from OCLC. Institutions also contribute new records and location information to WorldCat for items for which no record is found. Access to cataloging activities is provided by the Connexion client, Connexion browser, CatExpress, and Z39.50 cataloging.

OCLC Connexion
Integrated cataloging service that offers access to WorldCat, the OCLC Authority File and other online databases. The browser interface provides access via Internet Explorer or other browsers. The client interface provides access via Microsoft Windows-based software installed on user workstations. Both interfaces offer the same cataloging capabilities. Each also provides unique capabilities. The browser interface uniquely provides access to CatExpress, Dewey services, local holdings maintenance, and OCLC Selection and supports creation of pathfinders and other electronic resources. The client uniquely supports the use of macros, local files, offline cataloging, integrated label processing, using non-Latin scripts for cataloging, and batch processing searches and record actions.

OCLC Connexion browser
One of two interfaces to OCLC Connexion cataloging services and products. Introduced in mid-2002, the Web-browser-based interface provides the same access to cataloging in WorldCat as the Connexion client. The browser interface also provides some unique functions, including WebDewey and Abridged WebDewey, CatExpress, OCLC Selection, Pathfinders and Local Holdings Maintenance.

OCLC Connexion client
One of two interfaces to OCLC Connexion cataloging services and products. Introduced in the second half of 2003, the Windows-based software interface provides the same access to cataloging in WorldCat as the Connexion browser. The client interface also provides some unique functions, including the use of macros and an automatic macro recorder, extensive keyboard shortcut customization, integrated label printing, local files, offline cataloging, batch processing for searches and record actions, use of non-Latin-based multiscripts for cataloging, and more.

subject headings
The most specific word or phrase that describes the subject, or one of the subjects, of a work, selected from a list of preferred terms (controlled vocabulary) and assigned as an added entry in the bibliographic record to serve as an access point for retrieving records in a database.

A subject heading may be subdivided by the addition of subheadings (example: Libraries--History--20th century) or include a parenthetical qualifier for semantic clarification, as in Mice (Computers).

The use of cross-references to indicate semantic relations between subject headings is called syndetic structure.

A database of tens of millions of online records built from the bibliographic and ownership information of contributing libraries. The WorldCat database is the largest and most comprehensive of its kind. OCLC members use WorldCat for a full array of technical library services, including cataloging, interlibrary loan, reference, union listing, local holdings, and many more. WorldCat is the foundation of many OCLC services that let your library process, manage and share information resources. And with its records now opened to Web search, bookselling and bibliography sites, holdings in your collection are even more easily located and obtained by both your local patrons and a broad-based Internet usership.
