Rudolf Steiner´s notebooks

During his whole life Rudolf Steiner kept record of many ideas, concepts and experiences in notebooks of different sizes. More than 600 notebooks and 7000 slips of paper are preserved and serve  as a rich source for research work for texts, lectures and Steiner´s artistic work. Some thematic sketches could already be published in volumes of Steiner´s complete works (Gesamtausgabe, GA) and “ Beiträge zur Rudolf Steiner Gesamtausgabe”(Contributions)
