It would be nice to have a batch patron deletion tool like the batch patron modification tool that you load a list of cardnumbers or borrowersnumbers in to to delete the patrons. Of course we'd want some fail safes to make sure you don't delete patrons with fines or things checked out unless specified
I second the request. For our academic library, we need to do a batch deletion of patrons each semester to purge those who have graduated or withdrawn. An expiry date for patrons isn't helpful for this because students and faculty come and go at irregular intervals. I'm sure we wouldn't be the only ones to benefit from this.
Our library will be needing something like this also. NancyK Washoe County Library System
You can use a cardnumber list with the patron list tool and then use the patron list in the batch patron delete/anonymize. Still, it would be nice to make this an easier process.
