OutLook 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 letter are normalized)

010 - LCCN withCrossreferencing (hyphens and spaces are ignored, upper case letter are normalized)

Validation on all number matches on:

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

TEXT-BASED MATCH

245 $a (all characters) use filing indicator contatenated with $b (all characters) normalize upper case letters

Validate Leader position 6 and 7 (mandatory)

Validate 245 $h first 10 characters; $p first 10 characters as separate validation points, no concatenation

Validate 100, 110, 111 $a first 100 characters (hyphens and spaces are ignored, and upper case letters are normalized if more than one author tag, lowest numbered tag is used)

Validate 260 $b keyword search of first 5 words; match any one word; 260 $c match year with any of first 5 years

Note: Abscence of a VALIDATION subfield in any match point WILL inhibit an otherwise valid match.
We are recommending that the leader check be dropped for numeric matches.
