Serials Matching Algorithm

STANDARD BIBLIOGRAPHIC NUMBER MATCH

022 - ISSN withCrossreferencing (match on first occurrence - hyphens and spaces are ignored, upper case letters are normalized)

020 - ISBN withCrossreferencing (match on first occurrence - hyphens and spaces are ignored, upper case letters are normalized

Validation of all number matches on:

245 $a 10 characters (normalize upper case letters, special characters are ignored; checks field 008 position 35-37 for Language to decide which article to drop in the normalization of field 245)

TEXT-BASED MATCH

245 - all characters $a and $b

Validate 260 $b Publisher's name (first 5 words; match any one word); 260 $c Publisher's Date (first 5 dates)

Validate 245 $h - first 10 characters

Validate 100 $a - first 100 characters

NOTES:

  • Absence of a VALIDATION subfield for any matches in the Serials database 130 or 240 (uniform title) match would be more accurate than 245, however matching keys are predefined for the following field only: 001, 035, 010, 020, 022, 028 (with indicators 40 only), 245.
