Dedupe 2.6: Group 1 - 1XX $a - Main entry (Verify)
When an author (personal, corporate, or meeting) or a uniform title is used as the main entry of the record, the MARC record contains a 1XX tag.
- 100 Main entry -- Personal name
- 110 Main entry -- Corporate name
- 111 Main entry -- Meeting name
- 130 Main entry -- Uniform title
A MARC record may have only one 1XX tag, or no 1XX tag at all (in the case of a title main entry).
Only subfield a will be used for this verification parameter. If you want to use other subfields, please put a note in the online dedupe profile section 2-13.
This pertains to the number of characters to be used in the verification for the 1XX field within the verify method chosen above. The max number of characters that can be used is 2048.
Using Full verification with a length of 5:
1---5----10 $a Johnson, Mark
If the record had $a Johnson, Mark, then Johns would be used as the verify string.
This would mean that it would verify against all main entries that had $a Johns regardless of what followed. So $a Johnson, Mark would return a positive verify with $a Johns, Jason. In this case choosing a longer length, or using the default all may be more desirable.
Using Partial verification with a length of 11
1---5----11 $a Backstage Library Works
If the record had $a Backstage Library Works, then Backstage L would be used as the verify string.
Since the PARTIAL method was chosen, this would match against $a Backstage or $a Back. But it would not match against $a Backstage Travel.
Using Within verification with a length of 5:
1---5 1---5 1---5 $a Card, Orson Scott
If record had, $a Card, Orson Scott, then any combination of 5 characters could be used; Orson, Scott, or Card could be used.
This pertains to the number of words to be used in the verification for the 1XX field within the verify method chosen above.
