Subject: Teach marc_export how to export bibs for specified libraries
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=3cc4432ea3a3052365f0506f54044ff2298f3737;p=evergreen%2Fjoelewis.git

Teach marc_export how to export bibs for specified libraries

Useful shortcut for getting the bibs for libraries based on the
non-deleted callnumbers they have attached to non-deleted bibs.
Doesn't guarantee that they also have either a visible copy or
localized URI attached but whaddya want, magic? :)

Usage: marc_export --library BR1 --library BR2
