Well, you know after all this talk about Karl May, I'd find something like this:

Among untold others, Albert Einstein, Albert Schweitzer and Hermann Hesse professed
their unbridled appreciation of Karl May's work and their profound respect towards his
achievements. Even so, and even with his sales - including translations into most
European languages - over the years superseding those of any other German author, Karl
May was surprisingly neglected as an object of study by scholars. Isolated instances
of scholarly research - such as the German Heinz Stolte's doctoral thesis in 1936 on
Karl May's merits as an author satisfying deep-seated popular needs in an exemplary
manner or the Austrian Viktor Böhm's doctoral thesis in 1955 which probed into May's
writings from an angle of narrative power - were of no avail.
It was not until the early 1970's that Karl May's name and books began invading German
and non-German universities - a direct result of the founding of the
KARL-MAY-GESELLSCHAFT (Karl May Society, abbreviated KMG), in March 1969, by Professor
Dr. Claus Roxin, internationally renowned authority on Penal Law, and Professor Dr.
Heinz Stolte, then a highly esteemed leading figure at the Hamburg, Germany,
university, and a group of other earnest Karl May devotees. The Karl-May-Gesellschaft
aims at a thorough, wide-ranged and deep-probing analysis of the author's life and
works. As a matter of fact, during the past 25 years (1969 thru 1994) he has stirred
students' interests far more than have the established classical poets.
With close to 2000 members, in 20 different countries, the KMG ranks among the most
widely spread and most prominent literary societies. In return of annual dues of
(currently) 50 (fifty) Deutsche Marks, members receive a new 'Jahrbuch' (Yearbook)
every year (clothbound; 350-400 pp.), containing the latest scholarly reports and
essays, plus quarterly 'Mitteilungen' and 'Nachrichten' (bulletin and newsletter;
60-80 pp.). Research is based strictly on May's original texts as authorized by him
during his lifetime, not on post-war over-simplified editions aimed predominantly at
juveniles.
(Adaptations and abridged versions may be legitimately tolerated in our present-day
reading world, as appealing to readers for pure entertainment, along with
action-packed motion-picture adaptations of Karl May stories - featuring, for example,
Stewart Granger, Lex Barker, Herbert Lom, Elke Sommer - or exciting open-air stage
presentations; but all these naturally offer subjects of studies on their specific
grounds only, and are not to be confused with genuine Karl May matter.)
