What's new in CLZ Books Web? 2026

This is going to be THE main feature for 2026: Custom Fields!
The Custom Fields feature will let you create your own data fields, to catalog any information for which the software does not have a built-in field.

All fields you create will appear on a special Custom Fields tab of the Edit screen. And of course, you will be able to use the fields like any built-in fields, use them as columns, sort on them, use custom pick list fields as folders, add the fields to printed list, exports, etc..

And once the Custom Fields feature has been released for both the Web software and mobile apps, you will be able to sync them back and forth too!

Manage your Custom Fields

Use the Custom Fields screen to manage your custom fields, that is, add new ones, remove them, rename them, etc…

Adding a new Custom Field:

Choose from a wide range of field types. Create simple text fields, number fields, currency fields, yes/no toggles, big text areas (like Notes), even pick list fields and multi-value pick list fields.

Fill in your Custom Fields using the special tab in the Edit screen

ETA ?

The Custom Fields feature is in the final phase for the CLZ Web web-based software. We will release it for Web first, then later on bring the same feature to the CLZ mobile apps, allowing full syncing of Custom Fields between the Web and mobile!

ETA for Web: Feb 2026. Then for mobile a few months later?
Again, this is going to be THE killer feature for 2026!

In April 2025, we introduced one of the biggest new features ever: the automatic downloading of book values. The feature had been requested by many users for years, so the introduction of this feature was a huge success: Most users loved the new values!

However, a small group of users absolutely hated the new feature. They found the values annoying, not necessary, too “commercial”, irrelevant, etc…

We did not see that coming…. our fault. Maybe with our years of experience as software developers, we could have expected this. Guess we were too excited about the feature ourselves 🙂
Looking back, we should have made the entire feature optional from the start.

Of course, making it optional is still possible and that is exactly what we did for this update today. If you don’t want automatic values for your books, you can now disable downloading them via the new “Download Values” checkbox in the Settings screen (menu top left, then click Settings)

When you disable this setting, no book values will be downloaded anymore for any future books you add. On top of that it will also remove all automatic values you already have (any “My Values” you have will remain).
