jason points to singlefile, which looks like a pretty interesting application for organizing and sharing your book collection. i have quit a few books and have been mulling over looking into ways to organize everything for awhile. in fact, just yesterday i was digging through some stuff and found a cuecat scanner just begging to be hooked up with something like webqcat. i see that singlefile has an “isbn auto add” feature. i wonder if there’s any way to input isbns with cuecat? hmmm.
