Isbn issn

Description

Handles ISBN and ISSN values. As default whole record is marked as failed.

Notes:

• Non-hyphenated ISBNs are considered invalid in validate if hyphenateISBN is true.
• Hyphenation and moving invalid values result in duplicate fields, if similar fields exist in record already

Configuration

• hyphenateISBN: Add hyphens to ISBN. Defaults to false.
• handleInvalid: Invalid values are fixed by moving them to z- and y-subfields (ISBN and ISSN respectively). Defaults to false.
