Paper Lair: Library Manager

Is your lair (home) filling up with paper treasure (books)? Paper Lair makes managing your home library simple, modern, and effortless so you can spend less time organizing and more time enjoying your books.

Add Books Fast: Catalog your books in seconds with Open Library integration for quick book details and cover art:
- Barcode Scanner: Scan the ISBN barcode on the cover.
- Text Scanner (OCR): No barcode? No problem! Scan the printed ISBN directly from the copyright page.
- Manual Entry & Photos: Add books manually anytime, even offline, and snap a picture of your exact cover or pick one already in your device’s photo gallery.

Organize Your Hoard
- Custom Lists: Group your collection however you like: favorites, reading goals, genres, or custom shelves.
- Wishlist: Keep track of the treasure you are hunting for and move books to your library once they are in your hands.
- Quick Search & Sorting: Find any book in your collection instantly by title, author, or publication year.

Track Borrowed Books: Never lose track of a loaned book again. Easily record who borrowed your books and when, then mark them returned when they return to your shelves.

Safe & Private
- Offline First: Your library is stored on your device so it stays accessible even without an internet connection. The Open Library integrated features (book and cover lookups) do require internet access.
- Automatic Google Drive Backup: Keep your catalog safe and easily restore your data if you switch devices. This is turned on by default but you can turn it off if you wish.
- Privacy-respecting: Analytics and crash reporting are strictly opt-in. The data does help us with development but we understand if you are not comfortable sending it.
