You’re standing in your favorite bookstore, flipping through a novel that looks familiar. “Do I already own this?” you wonder.
You scroll through your phone photos, text a friend, mentally scan your shelves — but still, you’re unsure.
So, you buy it… only to get home and realize it’s already in your library. Sound familiar?
That’s exactly the problem BiblioBay solves.
It happens more often than we admit — you spot a great book in a store, only to realize later it’s already on your shelf. BiblioBay helps you avoid this by keeping your entire personal library in your pocket. With just one quick search or ISBN scan, you’ll instantly know whether you already own the book. Say goodbye to wasted purchases and the frustration of buying the same books twice.
If you’ve built even a modest personal library, you’ve likely run into this issue:
Especially for readers who frequent bookstores, secondhand shops, or book fairs, not knowing what you already own is both frustrating and expensive.
With BiblioBay, your entire book collection is just one tap away.
✅ Scan a book’s ISBN in-store and instantly see if it’s already in your personal library
✅ Search by title or author if scanning isn’t an option
✅ Add new books on the spot, so your collection stays up to date
✅ Leave notes or tags like “already own paperback, looking for hardcover”
No more guessing. No more duplicates. No more regrets.
