DIVISION OF BIBLIOGRAPHY (From the report of the chief bibliographer, Mr. Slade) Complementary to the abstract of evidence bearing on the origin and causes of the World War, now in course of preparation in the legislative reference service, under the requirements of Senate Resolution 339, and intended for use in connection with that abstract, is a bibliography dealing with the same subject, now in course of preparation in the division of bibliography. Work on the bibliography was undertaken by direction of the librarian on the adoption by the Senate of the resolution cited. As the work has progressed the task has proved by far the largest that has fallen to the division during the year. There are collections of books in Europe and the United States wholly devoted to the World War; their contents dealing with causes alone are in themselves so numerous as to form considerable libraries within the larger units. A single German bibliography on the question of responsibility for the war contains not less than 2,300 titles, of which 40 per cent are in languages other than German. There is, therefore, an abundance, in reality a superabundance, of material on the subject, though much relating to the war's origins remains unpublished that some day undoubtedly will become known. The subject. too, as is apparent, has out of its very nature intricacies leading to all but infinities. The bibliographical task before us is accordingly one of unusual interest and of unusual dimensions. The normal work of the division has, nevertheless, gone on steadily, and concurrently with it this special work. The latter has included much checking of lists and searching of catalogues in a survey of the resources of the Library through the many related or unrelated fields that widely different and still more widely differing writers have thought to contain roots of the war. The titles gathered have been incorporated in the bibliography, and the collections in the Library supplemented through the purchase of material not already contained in them. To turn from the matter of the bibliography on the origin of the war to the normal activities of the division of bibliography, the most considerable investigation made during the year was one resulting from a request from the office of the Attorney General for references to material having to do with the election of President and of succession to the presidential office. A chronological conspectus was made of Government documents on the subject; another of debates in Congress; and a bibliography on cards brought together giving references to numerous discussions in books and journals. Other special investigations have been conducted, and bibliographical lists and memoranda compiled as usual in the day-to-day service to Congress and the public. The lists compiled on special topics were 128 in number and had a total of 871 pages (mimeographed or typewritten). Number of memoranda compiled, 3,565. No statistics are kept of the number of readers and investigators advised on the premises. Acknowledgments of services rendered in the division of bibliography have been made by their authors in the following recent publications: "The life of Abraham Lincoln," by William E. Barton, Indianapolis, The Bobbs Merrill Co., 1925; "Washington Irving, Esq., ambassador at large from the new world to the old," by George S. Hellman, New York, A. A. Knopf, 1925; "Power of Congress over procedure in criminal contempts in 'inferior' Federal courts-a study in separation of powers," by Felix Frankfurter and James M. Landis, in Harvard Law Review, June, 1924; "William Graham Sumner," by Harris E. Starr, New York, H. Holt & Co., 1925. SMITHSONIAN DEPOSIT (From the reports of the librarian of the Smithsonian, Professor Corbin, and the assistant in charge of the deposit, Mr. Brasch) During the year there were two important changes in the staff. Mr. Paul Brockett, who had been connected with the Smithsonian Institution for 38 years and had served since 1902 as its assistant librarian and as custodian of the Smithsonian deposit, resigned to devote his full time to the duties of librarian and assistant secretary of the National Academy of Sciences. His successor, Mr. William Lee Corbin, formerly professor of English in Boston University, assumed the position of librarian of the Smithsonian Institution and custodian of the Smithsonian deposit on September 15. Mr. F. H. Parsons, assistant in charge of the deposit in the Library of Congress from 1900 to 1925, retired from the service January 22, 1925, in accordance with the provisions of the retirement law. For the greater part of the last six months of his term he had been absent from the Library on account of illness, his annual leave and sick leave being extended by leave without pay. He was able, however, to return to his work from January 1-22, 1925, thus rounding out his long service. During this period Mr. J. V. Butt, assistant in the division, supervised the work until October 16, 1924, when Miss H. W. Pierson, cataloguer for the division, was appointed acting assistant in charge. Miss Pierson supervised the work until the present assistant in charge was appointed, December 16, 1924. The opportunity for the division is a most attractive one. Nowhere is there in the United States a collection of transactions and proceedings of foreign and domestic scientific and learned societies of such magnitude, completeness, and importance. Many of the oldest and many nonexisting societies are represented in this vast collection. In conjunction with the scientific and technical books in the Library proper, this division is admirably equipped to serve as a reference and interlibrary loan source unique among libraries; for the deposit functions with all the Government scientific bureaus of research, including the Smithsonian Institution with its many departments of research and museums, the National Research Council, Carnegie Institution, and universities and colleges throughout the United States. One of the first of the large tasks recently undertaken was the arranging, listing, and checking of the large duplicate collection of publications of learned and scientific societies, which represents the accumulations of both the Library of Congress and the Smithsonian Institution for the past 25 years. Until now it had been impossible for the Smithsonian division to attempt dealing with this material, as neither of the two assistants could be spared from their other duties; but with the aid of a third assistant, Mr. Kelly, and in cooperation with Mr. M. A. Roberts, chief of the accessions division, it has been possible to push this work, and at present the Library's own collection has been completely listed, though not fully checked. The total number of duplicate society publications listed are 790 foreign and 56 domestic sets. In addition to this a large mass of duplicate university and college catalogues was recorded, then returned to the various institutions desiring to avail themselves of the offer of the Librarian of Congress to return this material under Government frank. Some 10,500 pieces were returned to 65 institutions, and approximately 2,500 pieces were destroyed as not being wanted by others. Along with this 4,000 pieces of old public-library reports were disposed of for old paper. During this process a great deal of miscellaneous duplicate matter was assorted and sent to several Government departments, namely, Agricultural library, Surgeon General's library, Smithsonian Institution, and War College library. The remaining collection was carefully searched by the assistant in charge of the Smithsonian division and was found to contain many old and valuable volumes, including some rare and out of print Americana. It is interesting to note how valuable this whole process has been. The most interesting bibliographical find was a collection of 85 original drawings and artists' proofs of the famous United States exploring expedition during the years 1838-1842 by Charles Wilkes, United States Navy. The work of searching this material in the public catalogue is now being systematically undertaken by the accessions division, with a view to retaining much for second copies or placing in the reserve collection. Mr. Roberts has also sent material from the sorting deck to this division for appraisement. One of the most interesting and probably most important phases in scientific training from an educational viewpoint in recent years has been the development of the cultural aspect of the sciences, namely through the history of science. This movement has assumed a very long-needed place in our university and college curricula. There are now one large and several smaller organizations or societies fostering the study and research in the history of the sciences in the United States. It is with this cultural phase of the sciences that the Library of Congress and the Smithsonian deposit must meet a growing demand, particularly for early scientific works, such as original sources and contemporary commentaries. However, while the Library is already rich in sixteenth, seventeenth, and eighteenth century sources in pure sciences, greater effort should be focused upon more of this sort of material. For instance, of the first edition of the great Copernicus "de Revolutionibus Orbium |
