One of the ways to provide access to (a version of) Wikipedia offline is Kiwix. Kiwix is a “reader” that will display the Wikipedia (a “snapshot” of Wikipedia in time, usually no more than a few months old) so that it can be read by users that are offline.
In order to use Kiwix, you need to:
- download the Kiwix reader
- download the special zim file that has the contents of interest. For example, here you can see all the contents that are available in Ukrainian
The big advantage of using Kiwix is that you can do 1 download and then just copy the files in thumbdrives and distribute those without needing an internet connection.
