three major sections, ( i ) bibliography and the theory of knowledge, (2) library administration and techniques and (3) the history of books and libraries. T h e most prominent librarians in all the Germanies have joined in giving homage to Vorstius, and the contributors include such well known names as Georg Leyh, Donker Duyvis, and Ilse Schunke. It would be difficult to do full justice to all the important essays that have been printed in this volume. T h e fact that the book was edited in East Germany for an East German has brought such essays as one by Todor Borov, director of the Bulgarian Bibliographical Institute, on the primary national bibliography of Bulgaria, Frantisek Horak, director of the Ceskoslovenska Akademie Ved. Zakladni Knihovna in Prague, on the library of the Czech Academy of Sciences, and Othmar Feyl, librarian of the University of Jena, on the classification scheme for the bibliographies of the book chambers of the U.S.S.R. Leyh's little essay entitled "Bibliographisches" is another useful contribution to library history. Fritz Redenbacher's study of the building problems of the University of Erlangen Library is instructive for any librarian who wrestles with spatial issues. Ilse Schunke's notes on library history in Dresden are based on her study of bindings. Wil l i Gober, director of the old University of Berlin Library (to be distinguished from the new Free University Library), reviews the old problems of centralization versus decentralization, showing a strong tendency to the former in the present day. Hugo Alker reviews the history of subject cataloging in the University of Vi enna Library for the past two centuries. Donker Duyvis writes on the international significance of the Index Bibliographicus.
