¶ Dedupe 4.13: Optional Group - 245 $h - GMD (Verify)
¶ Description
This field contains the title of the book, including main title, subtitle, statement(s) of responsibility, and occasionally other information appearing on the title page. Only subfield h will be used for this parameter.
Every MARC record must have a 245 field, but not necessarily a subfield h.
¶ subfield h - Medium
This subfield describes the medium, or form, of the work being catalogued. The terms used in $h are called General material designations, or GMDs, in AACR2. Subfield h is normally used only for various AV formats. When no $h is present, the catalogued item is presumed to be a book, serial, or other printed text item.
When subfield is used, the GMD is enclosed within square brackets. There is no punctuation before $h, and $h is not capitalized.
The terms deemed appropriate for $h are:
| activity card | art original | art reproduction | braille |
| chart | computer file | diorama | filmstrip |
| flash card | games | globe | interactive multimedia |
| kit | manuscript | map | microform |
| microscope slide | model | motion picture | music |
| picture | realia | slide | sound recording |
| technical drawing | toy | transparency | videorecording |
¶ Verify Method
- FULL - Full compares the full verify string up to the verify length.
- PARTIAL - Partial truncates the compare strings to the shortest string, then does a full compare. "The fox in the hound" in one record, "The fox" on the other record : both truncated to "The fox" and compared.
- WITHIN - Withing searches each compare string truncated at verify length against the full un-truncated string of the other field. "Cat" will ind a potential match on "The cat in the hat."
¶ Normalization
- NACO/CJK retains spaces and subfield delimiters.
- FULL is NACO normalization with all spaces and subfield delimiters removed.
