Each large boxed collection uses a copy of the Box Label database, from the shared "Collections Folder", to produce box labels, send emails, and create item records in ALEPH. The database can be emptied and re-used for each collection, provided that the "Autonumber" field is deleted and re-inserted after emptying. Click on the upper left corner of the data to highlight and press delete. Unlike an Excel spreadsheet, once you have started entering data, individual lines cannot be deleted or the numbering will become out of sequence. You can paste data over existing data, however.
