The Leader and the 008 Field in MARC Bibliographic Records

A Refresher Session for SIRIS Members, January 14, 2010

What is the Fixed Field?

• The leader together with the 008 field is commonly referred to as the “Fixed Field”

• Each bibliographic record consists of a fixed field, directory, the variable control fields (0XX), and the variable fields (01X-9XX)

• The 008 field is made up of character positions numbered from 00 through 39

• Some of the character positions are system-supplied• The data elements of the leader and 008 field are

positionally-defined, so that certain information (such as the date of creation) is coded in a consistent spot

Why Do We Use the Fixed Field?

• It contains coded information that is crucial for accurate searching and display of the information in the bibliographic record, such as:

• Type of material• Encoding level• Language• Collection or item level

Characteristics of the Fixed Field

• The fixed field has no indicators or subfield codes

• In SIRIS, the fixed field appears as the 000, 005, and 008

• The fixed field has a few mandatory data elements (depending on the format); other elements may be required if applicable, or optional. A helpful list of input standards is at http://www.oclc.org/bibformats/en/fixedfield/default.shtm

“The Leader” (Tag 000 in SIRIS)• Contains 24 character positions (numbered 00-23)

http://www.loc.gov/marc/bibliographic/bdleader.html

SIRIS Leader codes include:

• Record status (RecS)• Type (Type) • Bibliographic level (BLvl)• Type of control (Cntl)• Encoding level (ELvl)• Descriptive cataloging form (CatF)• Linked record requirement (Link)

The 005 Field

• Date and Time of Latest Transaction• Sixteen characters that indicate the date and

time of the latest record transaction and serve as a version identifier for the record

• Always System-Supplied

Example:005 19940223151047.0

The 008 Field: Fixed-Length Data Elements

• “Date” (00-05) is the system-supplied date that the record was entered (yymmdd)

• “DtSt” (06) is the type of date / publication status:

“s” for a single year (item level) “m” for multiple years (item level) “q” for a questionable date (item level) “i” for inclusive dates (collection level) “k” for range of years for the bulk of a collection

The 008 Field: Fixed-Length Data Elements

• Character positions 18-34 are defined independently for 7 different types of materials (Books, Computer files, Maps, Music, Continuing resources, Visual materials and Mixed materials)

http://www.loc.gov/marc/bibliographic/bd008.html

008

• “Dates” (07-10 for date 1; and 11-14 for date 2, when applicable) record the single year or range of years for the creation of the material

• “Ctry” (15-17), identifying the place of publication, production, or execution, is a 2 or 3 character code taken from The MARC code list for countries: http://www.loc.gov/marc/countries/cou_home.html

Ctry should reflect the location in the 260 $a, if any; use “xx#” if not applicable

008: Cataloging Source

• Character position 39, “Cataloging source” (SIRIS label: Srce) is a one-character code that indicates the original cataloging source of the record. Archival units should always use code “d”, since the Smithsonian is not a national bibliographic agency like LC or NAL (SIL sometimes uses code “c” for items cataloged for PCC or the Program for Cooperative Cataloging)

Where Can I Learn About the Fixed Field?

• The MARC Standards homepage (maintained by the Library of Congress)

• MARC 21 Format for Bibliographic Data (full and concise versions)

Manuscript Language Material (Leader Type: t)

• Type “t” is used for manuscript language material or a microform of manuscript language material

• 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 (unique) instance

• Examples: manuscript books and documents, marked or corrected galley and page proofs, legal papers, and unpublished theses and dissertations
