There is a bug report at
http://pkp.sfu.ca/bugzilla/show_bug.cgi?id=9019 where a bunch of us
are hammering out what changes are necessary to OJS to make it export
useful authority control information in MARCXML records in the OAI
If that's the kind of thing that interests you, or you know MARCXML
deeply, your contributions would be appreciated.
...let us be heard from red core to black sky
