The Encyclopœdia of Sexual Knowledge

The Encyclopœdia of Sexual Knowledge, published in 1934, is the first of a trilogy of sexual encyclopaedias by Arthur Koestler writing under the pen name of ‘Dr. A. Costler’. The second book is Sexual Anomalies and Perversions, Physical and Psychological Development, Diagnoses and Treatment; the title of the third book is, in the original French edition, L’Encyclopedie de la Famile [1] This third book was subsequently translated into English and published under various titles and with changes to the structure and text of the original edition. The name of ‘Dr. Costler’ as the author or co-author of the book is omitted from later editions.[2]

The first book contained chapters by two other authors; the second I wrote alone; the third contained chapters by Manes Sperber (who had been a practising Psychotherapist before he made his reputation as a novelist).[3]

Koestler wrote that working from standard text books and reference works "I condensed and distilled the Encyclopædia at a rate of about four thousand words a day." [4]

The background to Koestler’s collaboration in the writing of these books is set out in detail in his autobiography The Invisible Writing, Chapter XIX. ‘Introducing Dr. Coster’.

Contents

The book is divided into ten ‘Books’ (main chapters) and two Appendices. Each ‘Book’ consists of several Sections and Chapters. The book contains numerous monochrome illustrations and 32 colour plates. 836 numbered pages.
