To spread the principles of the Red Cross and the Geneva Conventions more widely throughout the world the ICRC has published a school textbook, which is now available in many languages. This is designed for school children and has been supplemented by a “Teacher's Manual”. These two works teach humanitarian ideals to young readers, but it was later found necessary to produce a manual for soldiers. The ICRC considered this matter and issued the “Soldier's Manual” which, like the school textbook, was generously illustrated.
