Where have you been all my library?

“Fantastic app! More than just a "you enter it all yourself," it references a database and enters most of the information for you. Less than ten books entered and only two were not found. Both have ISBN numbers but seem to be self-published, so not expecting those to be found. Even $15 to get full use of the app is definitely worth the price if you have a large collection. Highly recommended!” — The Kitchen Witch
