> Does it work for bulk files? -- It passed on a file containing 215 MARC Bibs and on a file containing 2,574 MARC Auth records. 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.
