From the reviews:„Finsler geometry is the most general among those geometries which satisfy certain highly natural conditions. … In the last fifty years many papers and more books appeared on Finsler geometry. So it became difficult to obtain a good overlook on the subject. The present Handbook aims to fill this gap. … The authors wrote well understandable parts. So the book is easily readable also with little knowledge on Finsler geometry.“ (Lajos Tamássy, Zentralblatt MATH, Vol. 1057 (8), 2005)
