Working with MARC

MaRC stands for Machine Readable Cataloging, and many folks in the code4lib community find themselves working with marc records at some point. This page is meant to be a round-up of the tools for working with marc. If you want a general introduction to the standard, the wikipedia article is a good place to start.

Getting Sample Data

One common question is where to get sample marc records for testing or playing around with. If you work at a library, chances are good that you can get some records out of your ILS (go ask your systems librarian if you don't know how to do this yourself). If you don't work in a library, you can get marc records from the internet archive at http://www.archive.org/details/marcrecords.

There is a nascent movement within the code4lib community to establish a test set of problematic marc records, especially records that are representative of the kinds of weirdness that is encountered in real libraries. It is hoped that this could eventually become a test corpus against which to run various marc processing implementations. For more information, watch Simon Spero's excellent talk from Code4LibCon 2010.
