|ALL: Leader/06 |
|ALL: Mandatory. One-character code. Default: Determined by format |
|All formats and 006 || |
The type of record. Use to differentiate records created for various types of machine-readable information and specific types of material.
In Connexion client, use the codes given here in the 006 field guided entry prompt for Type, except for the continuing resource 006, in which case use code s, which is not a valid code in the Type of Record fixed field. In Connexion browser, Type is identified by a label "006 fields for [format]" and a drop-down list with names for each Type instead of codes.
| ||Use the following guidelines to determine appropriate codes for materials whose designation may be uncertain: |
|Type material ||Guideline |
|Microforms ||Microforms, whether original or reproductions, are not identified by a distinctive type of record code. The type of material that was filmed takes precedence over the microform characteristics. Determine the type of material of the original item and use that format. Use Scores for microforms of scores, Books for microforms of books, Continuing Resource for microforms of continuing resources, Maps for microform of maps, Mixed material for microforms of mixed collections. |
|Theses (originals, reproductions, or copies) ||Determine the type of material of the thesis and use that format. For most book-like theses, use Books format and code t. For Scores theses, use code d. For Map theses, use code f. |
|Manuscripts ||Manuscripts are items written by hand or unpublished "single instance" items (a handwritten letter, hand-drawn map, handwritten score or galley proof). The handwritten or "single instance" characteristic distinguishes an item as a manuscript, compared with a mass printing, mass-produced or multiple-copy publications. Determine the type of material of the manuscript and use that format. Use code d for manuscript music, microforms of manuscript music and score theses. |
|Multiple kinds of material and collections ||Use code o when the entity is issued as a single unit and no type of material predominates. |
Use code p when the entity is a made-up collection and no type of material predominates. Use Ctrl (Type of Control) to indicate archival control status.
Use the code for the predominant type of material when the entity is a made-up collection and one type of material predominates. Use Ctrl to indicate archival control status.
|Archival items (single items) ||Determine the type of material of the item and use that format. Use Ctrl to indicate archival control status. |
|Single items with multiple characteristics (e.g., a slide that contains manuscript music.) ||Determine the main type of material and use that format. Optionally, enter coded data for the additional characteristics in field 006. Usually, choose the format that corresponds to the specific material designation in field 300 subfield ‡a. For example, if a slide contains manuscript music, use Visual Materials format for the slide. Optionally, enter coded manuscript music characteristics in field 006 for music scores. |
|Nonprint continuing resources, (e.g., a sound recording issued as a continuing resource or electronic or digital continuing resources) ||Determine the type of nonprint material and use that format. Use code b, s, or i in BLvl . Optionally, enter the coded continuing resource characteristics in field 006 for continuing resources. Nontextual continuing resources are no longer permitted on Continuing Resource format as allowable duplicates. |
|Broadsides ||Determine the type of material of the item and use that format. Use Books for textual broadsides, Scores for broadsides of musical scores and Visual Material for charts and other graphically oriented posters as appropriate depending on the purpose of the item. |
|Electronic resources || |
Determine the significant aspect of the electronic resource (language material, graphic material, cartographic material, sound, moving image, etc.) and code Type for that significant aspect of the content. Use code s in Form for the electronic aspect of the item. Also use the Computer File 006 field for the electronic aspect of the item, with appropriate coding of the File element.
Use code m only for these general classes of electronic resources: computer software, numeric data, computer-oriented multimedia and online systems or services.
|Integrating resources || |
An Integrating resource is a bibliographic resource that is added to or changed by means of updates that do not remain discrete and are integrated into the whole. Integrating resources can be finite or continuing. Examples include updating loose-leafs and updating Web sites. Use the Continuing Resources (formerly Serials) workform when creating records for textual integrating resources. For non-textual integrating resources:
- Determine the significant aspect of the integrating resource (graphic material, cartographic material, sound, moving image, etc.)
- Code Type for that significant aspect
- Code BLvl as i for integrating resource
- Continue to use the 006 field for Continuing Resources (formerly Serials) to create 006 fields for non-textual integrating resources
|BKS, CNR || |
|a ||Language material. Nonmanuscript language material, microforms of nonmanuscript language material and essentially textual electronic resources. |
BKS examples: Books, Pamphlets, Technical reports, Typescripts (multiple reproductions)
CNR examples: Periodicals, newspapers, annuals, journals, memoirs, proceedings.
Atlases (published): Use e for published atlases. Former practice was to use Books format. See "Code: Map."
|BKS || |
|t ||Manuscript language material. Language materials in handwritten, typescript (single instance) or computer printout, including printed materials completed by hand or by keyboard. The intention of these materials is usually, either implicitly or explicitly, to exist as a single instance. This includes marked or corrected galley and page proofs, manuscript books, legal papers and unpublished theses and dissertations. Use also for microforms of manuscript language material. |
|VIS || |
|g ||Projected medium. Filmstrips, motion pictures, slides, transparencies, videorecordings (including digital videos) and material specifically designed for overhead projection. All of the included media are intended for projection. |
|k ||Two-dimensional nonprojectable graphic. Cards, charts, collages, computer graphics, drawings, duplication masters, flash cards, paintings, photonegatives, photoprints, pictures, digital pictures, photo CDs, postcards, posters, prints, spirit masters, study prints, technical drawings, transparency masters, photomechanical reproductions and reproductions of any of these. Include any bound collections of reproducible masters. |
|r ||Three-dimensional artifact or naturally occurring object. Models, dioramas, games, puzzles, simulations, sculptures and other three-dimensional art works, exhibits, machines, clothing, toys, and stitchery. |
Also for microscope specimens (or representations of them) and other specimens mounted for viewing.
|o ||Kit. Mixtures of various components issued as a unit and intended primarily for instructional purposes. No one component is identifiable as the predominant component. |
Examples are packages of assorted materials, such as a set of K–12 social studies curriculum material (books, workbooks, guides, activities, etc.) or packages of educational test materials (tests, answer sheets, scoring guides, score charts, interpretative manuals, etc.).
|MIX || |
|p ||Mixed materials. Materials in two or more forms that are usually related by virtue of their having been accumulated by or about a person or body. The intended primary purpose is other than for instructional purposes (i.e., other than the purpose of those materials coded as o). This category includes archival fonds and manuscript collections of mixed forms of materials, such as text, photographs and sound recordings. |
|MAP || |
|e ||Cartographic material. Nonmanuscript maps, globes, atlases, aeronautical charts, navigational charts, celestial charts, remote-sensing images, computer-generated maps and other cartographic material. Microforms of nonmanuscript cartographic materials. |
Map continuing resource: Use code b, s, or i in BLvl . Optionally, enter coded serial characteristics in field 006.
Digital cartographic materials: Optionally, enter coded computer file characteristics in field 006.
Atlases (published): Use code e for published atlases. Former practice was to use Books format.
|f ||Manuscript cartographic material. Manuscript cartographic materials. Microform of manuscript cartographic materials and map theses. |
|SCO || |

Use the following guidelines for coding hymnals, operas, librettos and collections of songs with and without music:
With music—code c
- Use code c for hymnals with music either fully harmonized or with only melody.
- Use code c for publications of operas with words and music, either full scores, vocal scores, chorus scores or collections of arias.
- Use code c for collections of art songs (Lieder, melodies, etc.) with words and music.
- Use code c for collections of songs (e.g., popular, patriotic, national) with music.
Without music—code a
- Use code a (i.e., BKS format) for collections of songs without music.
- Use code a (i.e., BKS format) for hymnals with only text and no music and for collections of hymnal text not related to a particular hymnal.
- Use code a (i.e., BKS format) for separately published opera librettos with no music.
- Use code a (i.e., BKS format) for collections of art song texts, often published with translations.
Use the following guidelines for coding musical instruction materials:
- For items in LC classes MT170–MT950, use code c for items that are predominantly music.
- Use subject heading subdivisions as a tool in determining the correct Type code.
|Subdivision ||Code |
|Instruction and study ||Usually a |
|Methods ||a or c |
|Studies and exercises ||c |
|Orchestra studies ||c |
|Teaching pieces ||c |
|REC || |
|i ||Nonmusical sound recording. Nonmusical sounds (e.g., speech). Use also for sound effects; bird calls; physical exercise recordings (e.g., aerobic workouts) that consist of spoken, shouted, sung or chanted instructions over musical accompaniment; stories read over incidental music accompaniment and plays with incidental music. |
|j ||Musical sound recording |
|COM || |
|m ||Computer file. Items included in the following classes of electronic resources: computer software (including programs, games and fonts), numeric data, computer-oriented multimedia, online systems or services. For these classes of materials, if a significant aspect causes it to fall into another Type category, code for that significant aspect. |
Other classes are coded for their most significant aspect (e.g., language material, graphic or cartographic material, sound, music and moving image). In case of doubt or if the most significant aspect cannot be determined, consider the item a computer file. For additional information, see Cataloging Electronic Resources: OCLC-MARC Coding Guidelines
