Dedupe 2.4: Group 1 - 008 Date (Verify)
008 date
Verify Date: This is for verifying on the publication date used in the 008 date fields (positions 7-10 and 11-14.
Verify Method
Parameters in this verification allow partial dates to match to either full dates or other partial dates. Different methods are used in this FULL/PARTIAL/WITHIN.
- FULL compares both date1 and date2 of each record - both have to match.
- PARTIAL compares date1 of each record. If no match it compares date2 if the dates don't start with fill characters (space or |).
- WITHIN compares date1 of one record to date2 of the other and vice-versa. If no match it also does a parital verify.
Tolerance
The date tolerance for the Verify Date parameter is the number of years the date can differ and still qualify as a matched record. This allows for more leniency with hits on the 010/020 and stricter criteria for the TITLE or other fields. The tolerance allows for dates to match within a specified number of years.
Match exactly
The year 1996 can only verify with another record that has the year 1996. It will not match either 1995, 199u, 199-, or 199 (ends with blank).
Off by 1 year
The year 1996 would match either 1995, 1996, or 1997. It would not match 1994, 1998, or years where the ending digit is missing or contains a fill character.
Off by # years
This allows the year tolerance to be increased by the Library for two-plus years. This is helpful when the desired outcome is to match the same decade of the original year in question.
- Although Backstage recommends using the 008 date blocks, if these are missing or considered unreliable, please consult with Backstage staff for using the 260 $c publication date instead.
