"Hello! I wouldn't know where to begin. AllMyBooks has gotten so much better... But in random order what I like best about the program:
The interface is excellent!
Updating book information through numerous sites (Amazon.com/Amazon.de/Google and so on) especially seeing as I have lots of old books without ISBN number
The fact you can add not only the cover of a book but also illustrations
The fact that you can add a Biography (with picture) of the author
The virtual shelf (my idea to have this added hope others enjoy it) And on and on. There is just too much to mention!!! Overall it helps me keep track of the books I have and the location they are in. I even uploaded all to my website so whenever I am in an antiquarian bookshop and want to buy a book from them, I can have a look to be sure I don't already have that particular book (I sometimes forget if I already have a book)!!!"
