Publications, which appear under the brand E@I – our offline projects.

Note: The publications first appeared as side projects, which were often initiated at the request of the users of E@I’s online projects (for example, the lernu! CD and the Komputeko book). Most publications, like the online projects, are a result of online collaboration of an international team. However, the publications branch of E@I is becoming more and more popular, and will continue to grow in the future.
