Rae, 4000 records is not enough to cause any issues. My catalog is about 30,000 and MarcEdit runs just fine. I would guess there is some corruption in the file. I'd run MARC Validator and remove any records with issues. I might run Mnemonic Formatting Tools first. Remove any blank lines and remove any empty fields, then run the validator.

However, I end up with only 54 records. Am I taxing the code trying to process so many items? Background: We are converting from one library management system (Insignia) to another (Destiny) but have one mountain school with 26 students and a library of 6000+ copies. I don't want to buy a site license for this library and want to use either Libib or LibraryWorld. LibraryWorld allows import of MARC, but I can't seem to get there from the available exports in Insignia. Thus, trying to convert using MarcEdit. Thanks for any insight you might have!
