The electronic manual (PDF) was distributed by Pabst-Science-Publishers before 2016. If needed, you can ask the publisher yourself (firstname.lastname@example.org) if there are still copies available. A new edition of the manual is not planned.
The copyright of the manual is held by the KIDSCREEN group. Before printing and publishing parts of the manual (also in modified form), please send a request to Prof. Ulrike Ravens-Sieberer.
