Format Designation in MARC Records A Look Under the Hood Michael Doran Systems Librarian
Type Medium Format Form Terminology First, a few words about… overlapping meanings
AACR2 (1976) and AACR2R (1988) use format to mean a “particular physical presentation of an item” but the term does not appear in AACR (1967, 1970). * * http://www2.archivists.org/glossary/terms/f/format
Book Printed book Intellectual form Physical forms E-book (computer file) Audio book (e.g. on CD) Abstract => Concrete
Movie Film strip Intellectual form Physical forms DVD Streaming video Abstract => Concrete
This object is a…? Book (Bound) Serial Manuscript Artifact From a bibliographic perspective… Concrete => Abstract
Data Music/sound Video Software ??? CD ROM DVD Containing… Concrete => Abstract This object is a…?
limits.xml Add, remove, or rename “Format” limits in the limits.xml file.
“Category of material” MARC 007 Physical Description Fixed Field Positions of most interest are the 00, 01, (and 04) 00 Character position
MARC 007 Physical Description Fixed Field 00 Character position 01 Character position Once you choose a particular “Category of material” value, the remaining values in the 007 field are specific to that category.
MARC 007 Physical Description Fixed Field Count of bib records per 007/00 (UT Arlington Library - Voyager ILS) Seems to suggest that the 007 field is seldom used for books and serials. Mandatory if applicable (In “National Level Full”) Mandatory if applicable (In “National Level Full”)
“Type” format Based on the MARC Leader positions 06/07. Not all “types” are represented by default. Although there are additional “types” these 12 will likely cover about 99% of your collection. Not very user-friendly.
Based on the 007 field, but only on the first position – so missing a lot of granularity. Not all possible “formats” are represented. Probably roughly 1/3 of your collection will be included in the search if this is used as a limit. “Format” format
Traditional catalogs are not very user-friendly in regards to format limits.
Variable fields tend to be… well, variable A keyword search in UT Arlington’s WebVoyage OPAC for "dvd videorecording" (sans quote marks) yielded these 245 h variations -- within the first 10 search results: Human readable, and useful for retrieval via keyword searching. However non-normalized variable fields are problematic for indexing purposes and therefore for utilization in limits and facets.
When MARC records are imported into Voyager, these are the values that get indexed as “format”.
Terms like this also get indexed. However (in Voyager), they get indexed as keywords, not as formats.
MARC 008 Fixed-Length Data Elements One character position is “Form of item” Character position 23 for: Books Computer files Music Continuing resources Mixed materials Character position 29 for: Maps Visual materials The 008 field itself is mandatory for all records and the “Form of item” position is mostly mandatory for National Level Full records*. * National Level Full and Minimal Requirements, Control Fields http://www.loc.gov/marc/bibliographic/nlr/nlr00x.html 008 positions 18-34 definitions determined by “Form of material”
MARC 008 Fixed-Length Data Elements Values for “Form of item” Books Maps Music Continuing Resources Visual Materials Mixed Materials Computer files
MARC 008 Fixed-Length Data Elements 008 positions 18-34 definitions determined by “Form of Material” And “Form of Material Level I” is defined by? …our old friend, Leader positions 06-07* Form of Material Level I * 008 - Fixed-Length Data Elements-General Information http://www.loc.gov/marc/bibliographic/bd008.html

Count of bib records per 008/23 value for “Books” Form of Material (UT Arlington Library - Voyager ILS) (1,079,587 + 22,371) / 1,369,004 x 100 = 80% For most items, we only really know what it’s not. (1,079,587 + 22,371) / 1,369,004 x 100 = 80% For most items, we only really know what it’s not.
MARC 006 Additional Material Characteristics (Repeatable field) Because the 008 is not repeatable and is dependent on the Leader 06 and 07 for its definition, only one 008 can be included in a record…. The 006 field was created, as part of “format integration”, to record “additional aspects of an item”.   For details see: “Format integration and its effect on the USMARC bibliographic format” / Library of Congress. Network Development and MARC Standards Office
Count of MFHD records per 007/00 (UT Arlington Library - Voyager ILS) MARC 007 Physical Description Fixed Field No “Mandatory if applicable” requirements for MFHD 007 categories No “Mandatory if applicable” requirements for MFHD 007 categories
MFHD 007 Physical Description Fixed Field Indexing in Voyager However, not aware of Voyager utilizing the MFHD 007 for any WebVoyage functionality.
Bib MFHD Can holdings with different formats be attached to the same bibliographic record? Sure! printelectronic microform Are they? And should they be? (for your library) ??????
Voyager - Item Record Level Voyager uses item-record-level item types for circulation purposes.
Is dependent on how formats are designated in MARC records. Ability to effectively search and retrieve by the desired format. And how well the MARC format data is mapped and indexed.
