This unique interactive online system allows for easy, simultaneous, almost instantaneous access to all the information contained in the OESO books.

The broad accessibility of such a wealth of information can be considered the culmination of OESO's original approach.

The OESO Knowledge Interactive Information System represents the content of several OESO books already online, with all the various means of access, (by book or in all the books, by chapter, by author, by key words).

In addition, innovative additions have been introduced by OESO and the OESO Foundation: Audio reading of the texts, Video illustrations of some answers by extracts from Videoconferences organized in the framework of the OESO Foundation, and the new original method for updating the articles comprised in this unique wealth of information.
