Plans for the weekend: I'm going to scan the local anarchist bookshop's entire collection with a barcode reader, so they finally get an inventory. I'll probably use my little program which also checks whether a book is needed by the #InternetArchive. (Still works without changes 5 years later!)

Some 70 of those books are in the @internetarchive wishlist. They've been set aside and I'll see what to do about them.

Also, I've found my new arch-enemy: book cover designs where the ISBN barcode is printed in green or white (or anything other than black on white really).
