→Getting Sample Data: info on MARCXML for HathiTrust titles
=== 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 bibliographic records from the Internet Archive at [http://www.archive.org/details/marcrecords http://www.archive.org/details/marcrecords]. You can also get [http://www.hathitrust.org/data MARCXML data for titles in HathiTrust through OAI-PMH].
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 [http://www.archive.org/details/MARCTHULU Simon Spero's excellent talk from Code4LibCon 2010].
MARC records for authority data are more common. The [http://www.getty.edu/research/conducting_research/vocabularies/download.html Getty Vocabularies] makes both the The Art & Architecture Thesaurus (AAT) and The Union List of Artist Names (ULAN) freely available. The [http://www.library.northwestern.edu/public/gsafd/ Guidelines On Subject Access To Individual Works Of Fiction, Drama, Etc.] records are available from Northwestern University. The [http://www.nlm.nih.gov/mesh/filelist.html Medical Subject Headings (MeSH)] are available in many formats, one of them being MARC.
