The legacy data that libraries must deal with is often challenging to parse algorithmically. MARC is just the first layer--once you peel that back, you find that you have an elaborate mish-mash of elements, each of which with its own idiosyncrasies. This page is meant to serve as a place for the Code4lib community to track and share information, problems, methodologies, code, pseudo-code, etc. about nuts-and-bolts parsing of legacy library data.
