Extra info: Cost-free but not free software.

MJ - Not sure of the distinction. Do you just mean it's not "truly free", as in open-source? For everyone's information, I've downloaded it to my Win2000 machine, and it works nicely. Here's the statistical report on some of my recently downloaded MARC records. I've massaged it a bit, and used "0" to show tags present in all records, "a" for tags present in most of them, down to "x" for rare ones. Very helpful in figuring out my MARC-to-Koha DB linking prior to importing. I'm also using BookWhere to display the record contents in a very browsable and readable way, it also reports and let me filter based on topical Subject listings. And finally, MARCEdit to actually the records.
