Subject: LP1857060: Tests for ISBNs with 979 prefix
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=3831d36cfdad71bb9afbff03ac3ce9eb3ec0f499;p=Evergreen.git

LP1857060: Tests for ISBNs with 979 prefix

Also includes a slight tweak to the Amazon AddedContent code to avoid
attempting to convert 979 ISBNs to ISBN-10s (which is not possible).
