At first I thought it was a great program, able to search through the ISBN # of the books, until I went to put in the 31st book. It seems you cannot load anymore than 30 books into the free program, you must buy the full program. What a rip, dont bother with the free version, not worth the trouble to get all 30 of your hundreds of books loaded and have to reload them into a different program or buy the full version.
