Our new ILS (Biblionix Apollo) has an option to scan and upload an attachment to a patron record, so we're in the process of scanning, attaching, and then shredding our file cabinet of applications.  The thought it is that we still have it available to document (for us, adults (including parent/guardian) accepting financial responsibility for fines, fees, and damages), so we don't need to keep the paper copy.  New or updated forms are double-checked for accuracy by a circulation staff member and then processed for scanning and attachment before it's shredded.  We're making good progress on the project, considering we're only putting 4 hrs/wk towards it.

I'll be so happy when that cabinet is gone!  This is a management wishlist item for me.
