Over the course of his career, Klemm wrote and co-wrote a number of textbooks on inorganic chemistry which became standard textbooks in the field, repeatedly reprinted and translated.  These include: 
* Klemm, Wilhelm, Anorganische chemie (c1935). Berlin, Leipzig, W. de Gruyter & co. 
* Klemm, Wilhelm, Magnetochemie (c1936)  Leipzig, Akademische Verlagsgesellschaft m.b.H.  Considered a foundational text in magnetochemistry.
* Biltz, Heinrich,  Klemm, Wilhelm and Fischer, Werner. Experimentelle Einführung in die anorganische Chemie (1937), Berlin, Leipzig, Walter de Gruyter & Co. An introduction to inorganic chemistry using experimental methods. Beginning with the 21st edition in 1937, Heinrich Biltz was joined by co-authors Wilhelm Klemm and Werner Fischer. Their new version of the textbook became so well known that it was referred to as "BKF". At least 73 editions were published.
*  Klemm, Wilhelm, and Hoppe, Rudolf. Anorganische Chemie (c1979). Berlin ; Boston : De Gruyter, c1979. Anorganische Chemie by Klemm and Rudolf Hoppe has been described as a legendary work by two titans of solid state chemistry.
