[Koha] AMS (MSC) public sources?

[Balasa Rodica]

Hello Everybody,

I am working at installing Koha for IMAR (Institute of Mathematics of
the Romanian Academy), and it is highly important for them to configure
Koha to allow AMS (MSC) dictionary search. So I write to ask for advice
regarding the posiblity to import AMS from public sources of information
into MARC21 fields, if such sources exist.

Thank you very much in advance,
