1. Format Designation in MARC Records A Look Under the Hood Michael Doran Systems Librarian

2. Type Medium Format Form Terminology First, a few words about… overlapping meanings

3. 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

4. Book Printed book Intellectual form Physical forms E-book (computer file) Audio book (e.g. on CD) Abstract => Concrete

5. Movie Film strip Intellectual form Physical forms DVD Streaming video Abstract => Concrete

6. This object is a…? Book (Bound) Serial Manuscript Artifact From a bibliographic perspective… Concrete => Abstract

7. Data Music/sound Video Software ??? CD ROM DVD Containing… Concrete => Abstract This object is a…?

8. User interfaces

9. Patrons see two “format” choices: Type Format Voyager OPAC

16. MARC Record Leader and Control Fields (mainly fixed-position fields) Variable Fields

17. MARC Record

18. Important: Fixed field positions start at “0” MARC record Leader http://www.loc.gov/marc/bibliographic/ “Type”

19. 15 x 7 = 105 possible combinations (in theory) MARC record Leader “Type”

20. How many “type” combinations actually exist in a typical database?

21. In UTA’s Voyager database (of ~ 1,600,000 bib records): 53 However the 12 used for type limits encompass 99% of our bib records.

22. Count Voyager “Type” limit Count of bib records per Leader/06-07 combination (UT Arlington Library - Voyager ILS)

23. Count Voyager “Type” limit Count of bib records per Leader/06-07 combination (UT Arlington Library - Voyager ILS)

24. Using 12 Leader/06-07 combinations for “type” limits in Voyager LDR/06-07 Type Limit

25. WebVoyage HTML code LDR/06-07

26. limits.xml Add, remove, or rename “type” limits in the limits.xml file.

38. BIB_MEDIUM.MEDIUM 1-character field value is field 007/00 Missing out on valuable format information. Voyager Indexing

39. MARC 007 Physical Description Fixed Field

40. 36.8% of the collection

41. 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”)

42. What do we know so far?

43. “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.

44. 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

45. Traditional catalogs are not very user-friendly in regards to format limits.

46. How about discovery tools?

47. AquaBrowser

48. “This looks better!” It is better. But not as quite as good as it appears. two lists

59. MARC 245 Title Statement Subfield $h Medium

60. 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.

61. When MARC records are imported into Voyager, these are the values that get indexed as “format”.

62. Terms like this also get indexed. However (in Voyager), they get indexed as keywords, not as formats.

63. 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”

68. 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.

69. 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”.

72. What else have we learned?

73. Discovery tools employ a more sophisticated format mapping, but are still dependent on the underlying MARC data Format data exists in MARC variable fields as well as control fields

74. MARC… and other records Voyager records Bib MFHD Item

75. Voyager records Bib MFHD Item MARC… and other records We’ve been looking at Holdings Items Is there format designation at this level? Yes ???

82. 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) ??????

83. Voyager - Item Record Level Voyager uses item-record-level item types for circulation purposes.

84. 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.

85. Cataloging practice Cataloging records Catalog Process Product Technology Hat tip to Allyson Carlyle
