Scanning my collection of stuff
Apparently I have lots of duplicates

Next step is to get that turned into proper codes and then get it turned into actual US-MARC data, and then make that library useful

Annoyingly, apparently Dragon reused the same code several times for their issues, so I have 69 issues inside the 046363160340 block

Nice though
