Librarian Pro 6.0.7 macOS | 55 MB We all collect something, whether it's stamps, movies, games, music, books or wine. Librarian Pro brings sophistication and class to managing your collection! Browse all of your items at a glance on a virtual bookshelf, in a list, or in cover flow. Item artwork and information is easily and automatically downloaded from the web. Even track which items you have lent out to friends; or, for small businesses, go as far as recording late fees and due dates.
