I’ve posted a MarcEdit with a good number of enhancements, though if they are implemented correctly, you shouldn’t see most of them. Many are related to making Z39.50 client work better, fold some previous functionality back into MarcEdit and implement a few new pieces of functionality in the delimited text translator and Z39.50 Client.
BTW, anyone have a good translation between MARC21 and UNIMARC. I’d like to add a conversion between the two to make it easier for folks to use one or both, but I don’t have the UniMARC documentation handy.
