Microphotographic Atlas of Central European Woods - Mikrophotographischer Atlas der mittelopäischen Hölzer (Atlas microphotographique des bois d'Europe centrale), Eberhard Schmidt - Text in both english and german. (Series of publications by the Reich Institute for Foreign and Colonial Forestry n°1) - Schriftenreihe des Reichsinstitutes für ausländische und koloniale Forstwirtschaft n°1, herausgegeben von prof. Heske, Hamburg - (Série de publications de l'Institut du Reich de sylviculture étrangère et coloniale, Series of publications by the Reich Institute for Foreign and Colonial Forestry) - The chief task of this wood-atlas is to render possible an own wood identification to extended circles of botanists, wood-technologists, ethnologists, prehistorians and timber users. Such an atlas is the best help for solving this taks in a easy but also exact manner. He who is reading with atention the general descriptions of the wood structure which are preceeding the parts of the book discussing softwoods and hardwoods makes himself acquainted with the possibilities of the formation and arrangement of the wood elements ; then going through our illustrations he will be informed without trouble how distinctly each genus and frequently also the species of our woody plants are diffenet microscopically from one another. There is a short dichotomous key for identification given for the few softwoods easily to be overlooked. In the case of hardwoods, which are considerably more numerous, we do not give a key intentionally, as these keys often cause confusion when one of the mentioned characteristics is missing or badly marked.

Experience shows that wood-anatomy is a much neglected branch of science even in the circles of the wood-trade and industry and it also teaches that already the first acquaintance with this microscopic world calls forth a hight interest and brings about a new deeper relation to the material daily handled by the timber users.
The chief task of this wood-atlas is to render possible an own wood identification to extended circles of botanists, wood-technologists, ethnologists, prehistorians and timber users. Such an atlas is the best help for solving this taks in a easy but also exact manner. He who is reading with atention the general descriptions of the wood structure which are preceeding the parts of the book discussing softwoods and hardwoods makes himself acquainted with the possibilities of the formation and arrangement of the wood elements ; then going through our illustrations he will be informed without trouble how distinctly each genus and frequently also the species of our woody plants are diffenet microscopically from one another.
There is a short dichotomous key for identification given for the few softwoods easily to be overlooked.
In the case of hardwoods, which are considerably more numerous, we do not give a key intentionally, as these keys often cause confusion when one of the mentioned characteristics is missing or badly marked. Yet the synoptical table of hardwoods added to this book allows a much more positive restriction of the woods in question because the way to get to a right identification as to the characteristics is always left to the investigator's choice. The short process of such an identification by means of this table is presented by the example of oak. By the feature "ring-porous"our 46 genera are already reduced to 10. Only two of these ten, Quercus and Castanea, have radilly arranged vessels ; those two are again distinctly to be differentiated from one another by the ray-width. In such a way we have reached the aim without difficulty in three steps. Furthermore we have the possibility to examine all the rest of oak characteristics not applied in our identification process.
