Managing books from different sources
I have e-books that I bought on Amazon Kindle, Barnes and Noble Nook, and Kobo, plus ones that I bought as files I downloaded to my computer. Now that I am trying to organize it all, I may have made a bit of a mess. What I mostly want to know is whether I own a book, and where it resides. Is there a good software program for that kind of management?
Thanks,
