Sorting Incoming Cartridges for Duplication by Size

Hi all, we are 20-30% into Duplication, and I wonder how other libraries handle the returned cartridges and sizes.

• Do you write the size on them in larger letters, or, use some other means to sort them?
• We used the spreadsheet to take them off the shelves (still ongoing) but wonder the easiest way to sort them coming back.
• We have an inspection table we use for the DBs, but wonder if we can't improve on the small, printed size on the back of the cartridge.

All ideas welcome!
Thanks,
Maureen
