What's new in CLZ Books Mobile? 2025
Live today: a huge v10.2 update for your CLZ Books mobile app, with one big new feature:
Automatic book values
You can now get get values for your books from CLZ Core, based on average prices on various online used book stores. Values are automatically filled in when you Add Books from Core.
To get values for your existing books, use Update Values from the menu.
You can also use this, e.g. weekly, to get updates for the values.
Update Values in menu:
Update Values Report:
The book values are shown in the book details screen, near the top.
You can edit value related fields on the new “Value” tab in the Edit Book screen:
The Value is also shown in the List View:
Finally, view value statistics and most valuable book lists in the Statistics screen:
Other changes:
- The old “Current Value” field has been renamed to “My Value” and lets you either OVERRIDE the automatically provided value. Or just fill in a value for books that did not get an automatic value.
- Get automatic retail prices in the Retail Price field (previously named “Cover Price”).
- Optionally use the Retail Price as a “fallback value”, when an automatic Value is not available.
- Sort your book list by Value
What to expect for your book collection?
The values are based on average selling prices of books on several used book sites on the internet. This system is purely based on ISBN lookups and average ALL prices for the same ISBN.
This means that the system does not take into account the condition and completeness of your copy. The value will be “just” an average of all available copies.
Also: with close to 40 million books in our CLZ Core database, we will not be able to provide a value for all books in your collection. In particular, books without ISBN will not get values.
Currently, our Core and Cloud statistics show that CLZ Books users will get a value for around 83% of their books, on average.
Your mileage may vary of course. For example, if you own mostly mainstream US books with ISBN, your percentage may be closer to 90%. On the other hand, if you own mostly antique books, or only books in the Polish language, your coverage will probably be much lower.
The coverage of books with a value may slightly improve over time, as we are still gathering value information for less popular books.
Important: getting values from Core requires an actual subscription for the app
Yep, Values from Core is the first “premium” feature for CLZ Books!
To use the feature, you need to have an actual subscription for the app. If you are still using the app in “grandfathered status”, you will not have access to the values feature.
The solution is simple though 🙂 Start subscribing to the app today.
Just open the menu, then tap the “Subscribe Now” link under “Subscription Status”.
