I still have to add covers for the books that were already in the database, and maybe I'll work on that tomorrow. All the missing books, however, have been added.
Few of them were new enough to have ISBNs, and some of the covers were in pretty bad shape. I did the best I could fixing the cover scans, but I'm not very good at it.
Some of the books themselves are in less than good condition. Many of them have stamps from various used bookstores, and almost all of them have names or initials written inside, suggesting they've been through lots and lots of readers. A few are water-stained; at least two look like they might have been dropped in the bathtub!
Whether any of them are any good remains to be seen. . . .
