Morbus, I'm not sure what you are looking for is a library catalog. If you want access to individual articles, it can be done in MARC but there may be better options. There is bibliographic citation software, Endnote and Procite are some of the best known.
oss4lib lists Citation Manager as an OS project. See if that would meet your needs better. it would avoid the whole MARC thing. Sincerely, David Bigwood [EMAIL PROTECTED] Lunar & Planetary Institute Cataloging news: http://www.catalogablog.blogspot.com
