ROOT Documentation and Tutorials

The most recent information about ROOT can be found on the Root Homepage of CERN.

ROOT Class description

The ROOT Reference Guide offers a complete description of all ROOT Classes with view of the source code itself and all contained comments.

ROOT Users Guide

As manual for beginners and more experienced users, there is a ROOT Users Guide of about 300 pages available. It is distributed in the Adobe (.pdf) and Microsoft Word (.doc) format.

By default, GSI does not provide paper printouts of these documentations! However, if printouts for a larger number of users are requested, this may be done using the central GSI printing services.
