Catalogue every book you own — and every one you still want.
A personal library manager for Android. Organise by author and series, pull in rich details from open data, keep a wishlist, and choose where to buy — all without an account, and with nothing sent to SDS Apps.
Five of the screens you'll actually live in — from browsing what you own to tracking down a copy of something you don't.

Books group themselves under the authors and series they belong to, so a sprawling collection stays navigable. Sort by author, series or title, and see the format and edition of every copy without opening a thing.

Each book pulls together authors, descriptions, cover art and edition data from open, community-run databases — then lets you record what's true for your copy on top of it.

Look up anything by title or author and BookCollections searches open catalogues live — while clearly marking what's already on your shelves so you never buy the same book twice.

Keep a running list of everything you mean to get to. Filter it down in a tap, and when you're ready, move a book into your library or send it straight to the buy screen.

When you want a copy, BookCollections lines up the places that sell it and lets you choose — the big retailers, or the independents; brand new, or second-hand. Pick one and it opens in your browser or that shop's app.
Author and series grouping, sorting, formats and duplicate detection keep even a large, messy collection tidy.
Search open book databases and enrich every entry with descriptions, editions and cover art — no proprietary lock-in.
Save what you want and see where to buy it — new or used, big-name or independent — then finish in your browser.
No account and no SDS Apps server. Your library is stored on your device. The section below lists exactly what leaves your phone, and where it goes.
