We're using Koha 19.05.02 I have a txt file of biblio numbers that need to all have the contents of one field changed. 477 numbers (no dupes, I checked). I then went through the process of exporting these records. When I open the file in MarcEdit, it says I have 225 records. I don't know what happened to the other 252. I decided to go through the rest of the process, just to see if it worked as expected (this is why we have a test site). I edited the file, saved it as mrc and tried to import it to Koha. Where I got a very large error message saying nothing imported SOFTWARE ERROR, contact your webmaster. Unfortunately, the tech half of the team is away at the moment. . . so any help would be appreciated. I'm especially curious as to why I uploaded a list of 477 biblio numbers but I got only 225 records in return. I'm now going to experiment with batch editing within Koha. . . wish me luck!
