Dedupe 3.12: Group 2 - 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 $h are:
activity card - globe - picture - art original - interactive multimedia - realia - games art reproduction - kit - slide - braille - manuscript - sound recording - chart - music map - technical drawing - computer file - microform - diorama - microscope slide toy - filmstrip - model - transparency - flash card - motion picture - videorecording
Verify Method
- FULL - Full compares the full verify string up to the verify length.
- PARTIAL - Partial truncates the compare strings to the shortest string, then does a full compare. "The fox in the hound" in one record, "The fox" on the other record : both truncated to "The fox" and compared.
- WITHIN - Withing searches each compare string truncated at verify length against the full un-truncated string of the other field. "Cat" will ind a potential match on "The cat in the hat."
Normalization
- NACO/CJK retains spaces and subfield delimiters.
- FULL is NACO normalization with all spaces and subfield delimiters removed.
Length
This pertains to the number of characters to be used in the verification for the 245$h within the verify method chosen above. The max number of characters that can be used is 2048.
Words
This pertains to the number of words to be used in the verification for the 245$h within the verify method chosen above.
Defaults
The default for verifying on the 245$h within Hit Group 2 (245) is as follows:
- Must Verify if exists
- Full verify method
- NACO normalization
- NOTE: If you collections contains a lot of AV material, and, since AV material can vary so much from collection to collection, please consult with your Backstage project manager to ensure that the best profile parameters are being used.
