I have become recently unpleasantly aquainted with the world of Marc that is not Marc21, but is ISO 2709. What'll it do on ISO 2709? I might be able to dig up an example. I wonder if it'll claim it's Marc21 (not), or if it's Marc21 "Non-confirming" (no, it's not quite that either. It's ISO-2709 MARC that's not Marc21). If it just doens't know anything about it and says 'data', that's just fine, if it knows about Marc21 but not non-Marc21 ISO 2709.

Don't know if you consider these "bulk," but there is more than 1 record in each file (caveat: "file" stops after evaluating the first line, so of the 2,574 Auth records, the last 2,573 could be invalid). It failed on a file containing all of LC Classification. I need to figure out why. > >> Kevin, do you have examples of the output? > -- I received "MARC21 Bibliography" and "MARC21 Authority" respectively. In theory, if Leader 20-23 are not "4500" then "(non-conforming)" should be appended to the identification. If requested, the mimetype - application/marc - should also be outputted. > > Rgds, > > Kevin > > > > >> -----Original Message----- >> From: Code for Libraries [mailto:[log in to unmask]] On Behalf Of >> Ross Singer >> Sent: Wednesday, May 23, 2012 3:29 PM >> To: [log in to unmask] >> Subject: Re: [CODE4LIB] MARC Magic for file >> >> Wow, this is pretty cool. >> >> Kevin, do you have examples of the output? >> >> Does it work for bulk files? >> >> I mean, I could just try this on my Ubuntu machine, but it's all the >> way downstairs... >> >> -Ross. >> >> On May 23, 2012, at 3:14 PM, Ford, Kevin wrote: >> >>> I finally had occasion today (read: remembered) to see if the *nix >> "file" command would recognize a MARC record file.
