Our inventory is almost finished and I just noticed the pdf articles on inventory on this site. Of course I did completely opposite from the way suggested. It said to use the card catalog and then pull the book from the shelf. We are a small to medium library, I think. I had 3 volunteers helping so I made copies of the Accession sheets and we are going shelf by shelf pulling the books and marking them off on the copied sheets. When we are done with that I will create a master set and pull all of the books that were not found. Our Accession numbers are in the 4100's but I have a feeling we may have half that number. I really can't wait to see.
I wanted to do the inventory because I am entering all of our books in an Excel file. I just started using LibraryThing but I still want to have something I can print out. When I started putting the books in Excel, I stopped typing them onto the Accession sheets.
Is there a general rule about accession numbers. If you pull a book do you go back and use that number for a new book? My answer was no but I wanted to know what everyone else did.
