Restricted Section vs iLib

Never buy a book you already own. Restricted Section is your personal book catalog for iPhone. Scan the barcode on any book to add it instantly — cover art, author, series, and metadata included. When you're browsing a store or a friend's shelf, scan to check ownership in seconds. SCAN TO ADD Point at any book's barcode. Restricted Section looks it up via Google Books and adds it to your library automatically. No typing required. ENTER ISBN MANUALLY Can't scan the barcode? Type the ISBN directly and get the same instant lookup. CHECK BEFORE YOU BUY A single tap launches the Check scanner. Scan any book for an immediate answer — green checkmark if you own it, red X if you don't. No more duplicates. TRACK YOUR READING Mark books as Unread, Reading, Finished, or Wishlist. Add a 1–5 star rating and personal notes to any book in your collection. BROWSE BY SERIES Group your books by series and see which volumes you have — and which are still missing. BUILT FOR PRIVACY Everything stays on your device. No account. No cloud sync. No analytics. The only network requests the app makes are ISBN lookups to fetch book metadata — nothing personal ever leaves your phone. Restricted Section is free, open source, and built for people who take their bookshelves seriously.
