v4.3.9: Easily add books that come up as “Unrecognized ISBN”

January 18th, 2017

An important v4.3.9 update for your CLZ Books Android app is now available.

This update introduces an easier way to deal with “Unrecognized ISBNs”.
A new screen that not only helps you to add the book to your database anyway, but also helps your fellow CLZ Books users by instantly adding the missing ISBN to the CLZ Core central online book database.

(this feature was introduced for our Windows, Mac and iOS versions earlier, and in the meantime, people have used this new tool to add over 22 thousand new books to our Core!)

  • In the Add screen, when a scanned ISBN is not recognized, a new “Unrecognized ISBN” screen will appear.
  • In this screen, just enter the Author, Title, Publisher and Year, then click Add Book.
  • This will:
    1. Add the book to your own database, with the information you filled in.
    2. Add the book to our Core central online book database.

The result: for the next user who searches for this particular ISBN, it will be recognized 🙂

    • This will:
      1. Instantly add the ISBN/Author/Title entry to our Core online book database.
      2. Add the book to your own database with ISBN, Author and Title filled in AND linked to the new Core entry.

    In other words, this new screen not only helps you in adding unrecognized books, but it also helps your fellow CLZ Books users by adding the missing ISBN to the CLZ Core.
