The Historical Point of View 3 Giry's Manual of Diplomatics 1 is the most useful modern work. Of the historical atlases the most generally used is Historical that edited by Droysen, 2 but Schrader's 3 is excellent and atlases- contains a number of important special maps and plans as well as an index. A truly admirable and very inex- pensive collection of historical maps may be found in Putzger's cheap and unassuming Historical School Atlas. 4 This is in many ways as useful as Droysen, and in some respects actually superior to the more elaborate work. While but few of the aids to historical research are here given, those mentioned are of the utmost impor- tance by reason of the range and accuracy of the informa- tion which they furnish and of the ease with which they can be consulted. No really advanced work in history can be carried on without their aid. Many other useful works of the same class may be found in the lists given by Bernheim in the manual spoken of above. 1 Manuel de diplomatique, Paris, 1 894, 20 f r. 2 Allgemeiner historischer Handatlas, mit erlauterndem Text, Leipzig, M. 25. 3 Atlas de glographie historique, sous la direction de F. Schrader, Paris, Hachette, 35 fr. The only really adequate atlas in English is the Historical Atlas of Modern Europe, edited by R. L. Poole (Clarendon Press, $38.50), which is unfortunately far more expensive than the equally satisfactory German and French works of the same class. 4 Putzger's Historischer Schul-Atlas, edited by Baldamus and Schwabe. An American edition of this may be had, accompanied by an English translation of the German forms of the geographical names, New York, Lemcke and Biichner, $1.00. A new school Atlas of European History, edited by Professor Dow, is announced by Henry Holt.
