I have a small classroom library with a little over 300 books. I have all of the books cataloged on an excel document with the title, author, SRC points, and lexile levels. In addition I assign each book a number, stamp my name throughout the book, stick a library pocket in the back and put an index card with the assigned number so students can check out the book. I recently acquired about 350 more books. It would take me many, many hours to stamp and catalog these books. I'm not sure I want to dedicate the time. I'm looking for an easier way! How do you keep track of your books? Do you have any check out procedures so you know what students have what books?
