Thought I'd share this work put together by the folks in charge of our
consortium:

https://github.com/mcoia/sierra_marc_tools

It's a Perl implementation. I haven't used it myself, but I know it can
generate MARC records.

Subject: Re: [CODE4LIB] local APIs atop III's Sierra DB

i've done some very ugly, preliminary hacking at getting MARC records out:

https://gist.github.com/roblivian/7012077

generally "works", but still need to account for more invalid MARC tags,
"on-the-fly" records (non-MARC records, i.e. reserve items, ordered bibs,
etc)
