Home Library Software

I’ve been using CLZ Books (and its earlier desktop predecessors) for over twenty years, and it remains the gold standard for managing a serious home library. My collection now sits at nearly 4,000 volumes, almost entirely hardcovers, spread across multiple bookcases. CLZ has helped me keep everything meticulously organized—by author, genre, location, condition, purchase details, and more—without ever feeling overwhelmed.
The real game-changer has always been the mobile apps (iOS and Android). When I’m browsing in a bookstore or used bookshop, I can pull out my phone, scan the ISBN with the built-in camera scanner (which has an impressively high success rate), and instantly see whether I already own the title. No more accidental duplicates! That simple feature has saved me money and shelf space countless times over the decades.
What I appreciate most about the CLZ team is their ongoing commitment to improvement. They don’t just maintain the software—they actively listen to users and keep adding thoughtful features. The latest major update introduced individual Reading History tracking, which allows multiple read sessions per book with fields for Start/End Dates, Reading Status, Progress, and—best of all—a dedicated Reader field. My wife and I can now each log our own reading experiences on the same book entry (perfect for books we’ve both enjoyed at different times). Previously I relied on custom tags for this, which worked but felt clunky. The new system is far cleaner, more flexible, and syncs beautifully between the mobile apps and the web/desktop versions.
Beyond reading tracking, the app lets me customize almost everything: personal notes, ratings, locations in the house, purchase price and store, condition, and even custom fields for whatever unique details matter to me. Automatic cover art and core data (author, publisher, plot summary, genres, subjects) pull in reliably from their database, yet I can override anything if needed. Cloud sync keeps my entire collection backed up and accessible across devices, so I can update on my phone while traveling and refine everything on the big screen at home.
For anyone with a growing or already large collection—especially if you value accuracy, portability, and long-term reliability—CLZ Books is worth every penny of the subscription. The developers clearly care about bibliophiles like us, and after two decades, I’m still impressed by how much better it gets with each update. Highly recommended—whether you’re just starting to catalog or, like me, have been at it for years.
