Ex Libris Lookup — Know your books. Own your library. Ex Libris Lookup is a fast, private reference tool for readers, students, and librarians. Find the identifiers and details behind any book, build a personal library, and track your reading — all without accounts, ads, or tracking. Find any book Search by title, author, keyword, or ISBN and instantly pull the details you need. Or scan a book's ISBN barcode with your camera to search without typing a single character. Library identifiers at your fingertips Look up Dewey Decimal (DDC), ISBN, LCCN, ISSN, and ASIN numbers for cataloging, citations, and reference. Tap to copy any identifier in a moment. Your own library, on your device Save books to a personal library that lives entirely on your device — no cloud, no sign-in. Organize titles onto shelves, add books in bulk, and keep everything at hand offline. Scan whole shelves with AI (Pro) Point your camera at a bookshelf and let AI read the spines — add dozens of books to your library in one shot, no typing required. Smart collections (Pro) Build collections that organize themselves. Set rules — reading status, rating, format, Dewey class, subject, author, or tag — and books file themselves in automatically as your library changes. Shelf reports (Pro) Get an AI-crafted portrait of your library: its personality, highlights, and tailored suggestions for what to add next. Track loans and locations Lend a book without losing it. Record who borrowed what, set return reminders, and map your library's physical locations, room by room and shelf by shelf. Smart entry Adding books by hand is effortless. As you type, Ex Libris Lookup suggests authors and series drawn from your own saved library, so your catalog stays consistent and quick to build. Track your reading Mark books as want-to-read, reading, read, or did-not-finish. Record your current page to watch your progress, rate finished titles, and save memorable quotes and notes. Smart tags & summaries On-device text analysis suggests relevant tags and concise summaries for your books — processed right on your phone, never sent anywhere. For You recommendations Discover what to read next with personalized suggestions based on the tastes reflected in your own library. Statistics dashboard See your reading come to life with reading streaks, per-month charts, and insights into your habits over time. Citations made easy Generate clean citations in MLA, APA, Chicago, or BibTeX for any book in your library — perfect for essays, papers, and bibliographies. Private by design Ex Libris Lookup collects no personal information and requires no account. Everything you save stays on your device. Book searches are sent only to open book catalogs (Open Library and Google Books) to fetch results, and Pro's AI features send only the shelf photo or book list needed to generate results — nothing is sold or shared. The app sends a small number of anonymous, device-level diagnostics (such as anonymized purchase-error reports) to help us fix problems — these contain no personal information and are never used for advertising or tracking. No ads, no third-party trackers, no accounts — ever. Book data is provided by Open Library (openlibrary.org) and Google Books. Ex Libris Lookup is not affiliated with either service. Ex Libris Pro is an optional auto-renewing subscription ($4.99/month or $29.99/year). Payment is charged to your Apple Account at confirmation of purchase, and the subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings. Privacy Policy: available in the app under Settings → Privacy Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | Ex Libris Pro Annual | $29.99 | per year | | Ex Libris Pro Monthly | $4.99 | per month | ## Version history (last 5 releases) ### 2.0.2 — 2026-08-11 Ex Libris Lookup 2.0.2 — Know your books.
