A Free Utility Built for Collectors

Some book catalog apps trap your collection behind monthly recurring subscriptions or limit the amount of books you can add for free.  Paper Lair does not take this approach.  Instead we decided to make Paper Lair ad-supported so that cataloging your home shelves, no matter how full they are, remains genuinely free and straightforward for every reader.
