Book Collector Pro is a software application that enables users to catalog their book collections. It offers the possibility of sorting books by different criteria, as well as keeping track of the items that were loaned. Multiple databases can be created, and books can be added by either performing an automatic search process or by manually entering the details about each book. Obviously, the first option simplifies the entire process of creating a book collection, as it allows users to look for books by ISBN, author and title, or LCCN.
