The original Book module has been part of Moodle as a standard plugin since version 2.3.
The Interactive Book module builds on that foundation as its successor, introducing key improvements in usability, security, and interactivity. While it retains the familiar structure, it’s designed to offer a more modern and engaging experience for both educators and learners.

I am using moodle 2.1 version. I have installed modbook plugin. And I added one book to the course. Then I am trying to add bulk chapter to book. But, I didn't find option "importing chapter into book : 'import'" in editing chapter page. But, in http://moodle.aub.edu.lb/mod/book/view.php?id=73722&chapterid=2093 this documentation they mentioned. I am adding courses, books and chapters as Administrator. Please help for this issue.
This version was in release 2.0rc (20110320) and it doesn't appear to be available via git. Where or how do i obtain a clean, vanilla copy?
and another question...is it possible for the student to mark a chapter as readed???
How would I do it?
