I'm installing Koha for a customer that want to use AMS (American Mathematical Society) in it's MARC records. I can't find where to store AMS in MARC.

Hi, in fact you need to use the tag for the "Other Class Number". For Marc 21: tag 084 with subfield $2msc For Unimarc: tag 686 with subfield $2msc <is only a suggestion, I don't find a code form for the classification of AMS in Unimarc>

-- Paul was bang on with the MARC codes for the classification numbers. If you are using MARC21, you will probably also want to take note of the thesaurus you are using (I am assuming if you're using AMS you are not using LCSH), so in your subject tags (6xx), you'll add another $2msc BTW, Library of Congress lists -- msc Mathematical subject classification (Providence, RI: American Mathematical Society) -- in its notes for FIELD 084 under Part III, Classification Sources, (URL <http://www.loc.gov/marc/relators/relaclas.html>) of its MARC Code Lists for Relators, Sources, Description Conventions (URL <http://www.loc.gov/marc/relators/relahome.html>), so Paul was right on that account as well! In practice, Zeno, your library may choose to omit the $2 subfield in 6xx fields (CISTI in Canada does) but it's more friendly and better cataloguing practice to include an identifier for the subject heading/thesaurus used. Hope this little addendum to Paul's answer helps. Cheers, Steven F. Baljkas library tech at large Koha neophyte Winnipeg, MB, Canada
