Substantially the books contain three parts each:

• The reprint of Grasemann’s "Reverend"; its first edition was a small booklet of 56 pages, self-published by Grasemann in 1982 and meanwhile out of print for a long time. Despite its outer smallness it was a very important publication and surprisingly rich in content, dealing with the modern conception of the theory of the logical (new-German) problem and its evolution from the very beginning in the 19th century. As the book is also available in English now, non-German speaking readers will be able to study for the first time in detail the thinking and the ideas of the new-German problem school.
• The essay "Pläne, Spiele, Züge" [Plans, Lines of Play and Moves] by Stephan Eisert and Hans Peter Rehm, reprinted from Die Schwalbe 48, XII/1977, p. 137-151 and slightly revised by the authors, informs us "about some newer developments in the logical school".
• "A Florilegium. A choice selection of logical chess problems. Selected and with comments by Hans Peter Rehm and Stephan Eisert" gives 82 more recent problems with elaborate and sophisticated comments.

Moreover the books contain forewords by Schwalbe chairman Hans Gruber and by Hans Peter Rehm, a two-page biography of Herbert Grasemann, also written by HPR, a bibliography, a German/English glossary of technical terms, an index of names and of the most important terms & themes, as well as a number of photos of problem composers who played an outstanding role in the history of the new-German (logical) school.

The brilliant style of the three authors Grasemann, Eisert and Rehm, in combination with all the excellent problems make for a great reading pleasure. I can only recommend this book warmly to all people interested in chess problems.
