Leader (NR)

Encoding level (Leader/17) of the record has been changed to a higher encoding level.

Addition/change other than in the Encoding level code has been made to the record.

Record has been deleted.

Record is newly input.

Prepublication record has had a change in cataloging level resulting from the availability of the published item.

Used for non-manuscript language material. Manuscript language material uses code t.

Used for printed, microform, or electronic notated music.

Used for manuscript notated music or a microform of manuscript music.

Used for non-manuscript cartographic material or a microform of non-manuscript cartographic material.

Used for manuscript cartographic material or a microform of manuscript cartographic material.

Used for motion pictures, videorecordings (including digital video), filmstrips, slide, transparencies or material specifically designed for projection.

Used for a recording of nonmusical sounds (e.g., speech).

Used for a musical sound recording (e.g., phonodiscs, compact discs, or cassette tapes.

Used for two-dimensional nonprojectable graphics such as, activity cards, charts, collages, computer graphics, digital pictures, drawings, duplication masters, flash cards, paintings, photo CDs, photomechanical reproductions, photonegatives, photoprints, pictures, postcards, posters, prints, spirit masters, study prints, technical drawings, transparency masters, and reproductions of any of these.

Used for the following classes of electronic resources: computer software (including programs, games, fonts), numeric data, computer-oriented multimedia, online systems or services. For these classes of materials, if there is a significant aspect that causes it to fall into another Leader/06 category, the code for that significant aspect is used instead of code m (e.g., vector data that is cartographic is not coded as numeric but as cartographic). Other classes of electronic resources are coded for their most significant aspect (e.g. language material, graphic, cartographic material, sound, music, moving image). In case of doubt or if the most significant aspect cannot be determined, consider the item a computer file.

Used for a mixture of various components issued as a unit and intended primarily for instructional purposes where no one item is the predominant component of the kit.

Used when there are significant materials in two or more forms that are usually related by virtue of their having been accumulated by or about a person or body. Includes archival fonds and manuscript collections of mixed forms of materials, such as text, photographs, and sound recordings.

Includes man-made objects such as models, dioramas, games, puzzles, simulations, sculptures and other three-dimensional art works, exhibits, machines, clothing, toys, and stitchery. Also includes naturally occurring objects such as, microscope specimens (or representations of them) and other specimens mounted for viewing.

Used for manuscript language material or a microform of manuscript language material. This category is applied to items for language material in handwriting, typescript, or computer printout including printed materials completed by hand or by keyboard. At the time it is created, this material is usually intended, either implicitly or explicitly, to exist as a single instance. Examples include marked or corrected galley and page proofs, manuscript books, legal papers, and unpublished theses and dissertations.

Monographic bibliographic unit that is physically attached to or contained in another unit such that the retrieval of the component part is dependent on the identification and location of the host item or container. Contains fields that describe the component part and data that identify the host, field 773 (Host Item Entry).

Serial bibliographic unit that is physically attached to or contained in another unit such that the retrieval of the component part is dependent on the identification and location of the host item or container. Contains fields that describe the component part and data that identify the host, field 773 (Host Item Entry).

Made-up multipart group of items that were not originally published, distributed, or produced together. The record describes units defined by common provenance or administrative convenience for which the record is intended as the most comprehensive in the system.

Part of collection, especially an archival unit described collectively elsewhere in the system. Contains fields that describe the subunit and data that identify the host item.

Bibliographic resource that is added to or changed by means of updates that do not remain discrete and are integrated into the whole. Examples include updating loose-leafs and updating Web sites.

Item either complete in one part (e.g., a single monograph, a single map, a single manuscript, etc.) or intended to be completed, in a finite number of separate parts (e.g., a multivolume monograph, a sound recording with multiple tracks, etc.).

Bibliographic item issued in successive parts bearing numerical or chronological designations and intended to be continued indefinitely. Includes periodicals; newspapers; annuals (reports, yearbooks, etc.); the journals, memoirs, proceedings, transactions, etc., of societies; and numbered monographic series, etc.

No type applies to the item being described.

Material is described according to archival descriptive rules, which focus on the contextual relationships between items and on their provenance rather than on bibliographic detail. The specific set of rules for description may be found in field 040, subfield $e. All forms of material can be controlled archivally.

Character coding in the record uses the 8-bit character sets described in MARC 21 Specifications for Record Structure, Character Sets, and Exchange Media. Non-default character sets used are identified in field 066.

Character coding in the record makes use of characters from the Universal Coded Character Set (UCS) (ISO 10646), or Unicode™, an industry subset.

Most complete MARC record created from information derived from an inspection of the physical item.

Next most complete MARC record after the full level created from information derived from an extant description of the item (e.g., a printed catalog card or a description in an institutional guide) without reinspection of the physical item. Used primarily in the retrospective conversion of records when all of the information on the extant description is transcribed. Certain control field coding and other data (e.g., field 043 (Geographic Area Code)) are based only on explicit information in the description.

Less-than-full level record (i.e., a record that falls between minimal level and full) created from an extant description of the material (e.g., a printed catalog card) without reinspection of the physical item. Used primarily in the retrospective conversion of records when all of the descriptive access points but only a specified subset of other data elements are transcribed. Authoritative headings may not be current.

Brief record that does not meet minimal level cataloging specifications. Headings in the records may reflect established forms to the extent that such forms were available at the time the record was created.

Less-than-full but greater-than-minimal level cataloging record that meets core record standards for completeness.

Preliminary cataloging level record that is not considered final by the creating agency (e.g., the headings may not reflect established forms; the record may not meet national-level cataloging specifications).

Record that meets the U.S. National Level Bibliographic Record minimal level cataloging specifications and is considered final by the creating agency. Headings have been checked against an authority file and reflect established forms to the extent that such forms were available at the time the minimal level record was created. The U.S. requirements for minimal-level records can be found in National Level and Minimal Level Record Requirements

Prepublication level record. Includes records created in cataloging in publication programs.

Used by an agency receiving or sending data with a local code in Leader/17 cannot adequately determine the appropriate encoding level of the record. Code u thus replaces the local code. Not used in newly input or updated records.

Concept of encoding level does not apply to the record.

Descriptive portion of the record does not follow International Standard Bibliographic Description (ISBD) cataloging and punctuation provisions.

Descriptive portion of the record and the choice and form of entry of the access points are formulated according to either the second edition of the Anglo-American Cataloguing Rules, 2nd Edition (AACR 2) or cataloging manuals based on AACR 2, which follow ISBD in their descriptive cataloging sections. The punctuation practices of ISBD apply.

Descriptive portion of the record is formulated according to the descriptive and punctuation provisions of ISBD. Heading forms are not formulated according to AACR 2.

Institution receiving or sending data in Leader/18 cannot adequately determine the appropriate descriptive cataloging form used in the record. May be used in records converted from another metadata format.
