Helmut Wirth (1973): Max Reger in Selbstzeugnissen und Bilddokumenten. Rowohlt Taschenbuch Verlag GmbH. ISBN 3 499 50206 2. A concise but comprehensive introduction to Max Reger's life and work (in German). Contains a work list, richly illustrated. Still available? Bargain.
Bettine Reichelt (2005): Max Reger - Ein biographischer Roman. Evangelische Verlagsanstalt Leipzig. ISBN 3-374-02210-3. This is one of the newer additions to the Reger - library. Although the book starts with a sympathetic feeling for Max Reger, it seems as if the author's sympathy gradually shifts to Elsa Reger whose personality is depicted much better and livelier than that of Max. Where some chapters are nicely written, some contain complete nonsense: the text on pages 158 - 159 is easily falsified against the account given by Adalbert Lindner (1923, pages 136 - 137)). Why the focus has been laid so strong on the Wiesbaden years (148 of a total of 275 pages) remains a mystery, but it effects an unbalanced total result as the later years are only shortly dealt with.
Guido Bagier (1923): Max Reger, mit 17 Bildern. Deutsche Verlags-Anstalt Stuttgart Berlin. No ISBN. Still the best Reger biography and discussion of his works (in German). Unfortunately never reprinted and only available second-hand or in libraries (I have a complete scanned version on CD, available for those interested).
Adalbert Lindner (1923): Max Reger. Ein Bild seines Jugendlebens und künstlerischen Werdens. J. Engelhorns Nachf. Stuttgart. No ISBN.Very sympathetic written book by the hand of Reger's first music-teacher. For those interested in details about Reger's personality. In German and printed in the old-fashioned German-Gothic font. Only available second-hand or in libraries.

Hedwig & E.H. Müller von Asow (ed. 1949): Max Reger. Briefwechsel mit Herzog Georg II. von Sachsen-Meiningen. Mit 17 Bildtafeln und 4 Faksimiles. Verlag Hermann Böhlaus Nachfolger. Weimar. No ISBN. Life at a small German "Hof" between 1912-1914. Letters of Max Reger and Herzog Georg II. Although Reger always destroyed the received correspondence, he made two exceptions: letters from Karl Straube and from Herzog Georg II. This book is a Virtual Reger-diary of the Meiningen years, illustrating his immense number of concert-representations and his daily problems. Written in a beautiful, literary German. For those who want to know details about Reger's daily life.
Susanne Popp und Susanne Shigihara (eds. 1985): Max Reger - Briefwechsel mit dem Verlag C. F. Peters. Dümmlers Verlag Bonn. ISBN 3-427-86361-1. One of the most interesting books about Max Reger! It contains much information about his works, his thoughts and the relation with his publishers. Several facsimiles are included. Explaining texts and notes of the editors are very useful and interesting for reading. The publication is scientifically prepared but easy to read.
Susanne Popp (ed. 2005): Max Reger - Briefe an den Verlag N. Simrock. Carus Verlag Stuttgart. ISBN 3-89948-063-5.

Else von Hase - Koehler (ed. 1928): Max Reger - Briefe eines deutschen Meisters. Ein Lebensbild herausgegeben von Else von Hase - Koehler. Koehler & Amelang, Leipzig. No ISBN. Although some disputes may arise as to the degree of editing of the original texts (e.g. Fritz Stein 1939, page 25), this book provides a lively impression of Max Reger's personality. Even today, it is an awful feeling when after reading the last letters the consiousness arises that suddenly there will be no letters anymore.....

Helmut Brauss (1994): Max Reger's music for solo piano. The university of Alberta Press, Edmonton. ISBN o-88864-255-5. Available as a bargain via the internet. The best introduction to Reger's piano music (in English). The piano being still an easily available instrument, Max Reger's works for this instrument are often automatically the first introduction to his musical world. This book uses a critical and scientific approach but is surprisingly easy to read. It contains numerous musical examples and analyses of individual works. Therefore, it is invaluable for Reger-admirers, students and professional pianists alike.
