In this directory called "Kerekjarto_Flaechentopologie", you have, in `djvu' electronic form, a famous book that is by now now rare outside German-speaking countries: B. von Ker'ekj'art'o, ``Vorlesungen ueber Topologie I: Flaechentopologie'', based on the paper edition in `Die Grundlehren der mathematischen Wissenschaften', Band 8, Springer Verlag., 1923. This book is one of the high points of early geometric topology. Electronic reproduction was by Hermann Haehl, Lucien Guillou, and Laurent Siebenmann (who encourage others to achieve still better image quality). For other works by von Ker'ekj'art'o, see .
