There are few handbooks devoted to clinical neuropsychology or behavioral neurology written in French. Most recently, there have been two: one by Habib and the other edited by Seron and Jeannerod. This revised and improved edition of the book edited by M.I. Botez completes this short list. The Botez book is impressive in terms of both its form and its content. The first edition, published in 1987, had 413 pages, 36 collaborators, and 37 chapters. The new edition has 682 pages, 55 collaborators, and 37 chapters. Fourteen of the chapters are quasi-exact reproductions of those in the first edition, while the others have been modified or added.
