K-Library is a .klib reader. In Kaldus, the National Library will have access to thousands of books with using the .klib format. These files can also be used with ebook tablets to allow a person to markup notes on the file. The K-Library app will handle all of that.
To make the best use of the K-Library app, one would want to acquire an Kaldan Library account. Of course, this will be required for setting up an account as with all Kaldan companies, but this would be simple enough for anyone with a GIN, and an NIN.
