Okay DigiPresHiveMind, I have a question... I have a big pile of MARC XML. I don't know MARC, so unlike the experts I've worked with, I can't expand all these letters and codes in my head! Is there a library that will do some basic expansion of MARC into something I can understand? I realise this might be lossy, but some kind of Dublin Core or plain-old-CSV projection would be helpful!
