FAMOUS BOOK /COLLECTIONS IN AMERICAN LIBRARIES.One of the world’s best collections of books on Turkey and the

Balkan states is in an American library. It is the famous Riant col-lection now in Harvard University library, and is interestingly de-scribed in a bulletin just issued by the United States Bureau ofEducation. It was acquired by Harvard in 1899 and has since beenadded to, until today the section on the Ottoman Empire comprisesabout 4,000 volumes.American libraries have a very large number of valuable special

collections. What is proba-bly the most important Dante collectionin existence is at Cornell, and the same institution has a collectionon the French Revolution that experts say can hardly be surpassedeven in France. The most remarkable set of Bibles in the world,comprising a large number of first editions and unique copies, is inthe library of the General Theological Seminary in New York. NewYork City also has one of the most ’nearly complete collections ofbooks on Hebrew subjects, that in the Jewish Theological Seminary,consisting of 33,000 volumes. One. of the finest libraries of Japanesematerial to be found anywhere is at Yale University. In works onmystic subjects it would be difficult to duplicate in Europe the greatcollection in the Masonic Library at Cedar Rapids, Iowa, or the sim-ilar collection of books and manuscripts on ritual and ceremonialin the Massachusetts Grand Lodge of Masons at Boston.For a great collection of works on German socialism the expert

need not look to Germany; he can find it in the United States. Atthe Wisconsin State Historical Library, at Madison, is the Schluetercollection, containing many works not found even in the archives ofthe German Social Democracy in Berlin.In music the Newberry Public Library of Chicago has a conspicu-

ous collection, especially rich in works on the history and theory ofmusic by Italian authors.On the side of science, the Carnegie Library of Pittsburgh con-

tains about 40,000 volumes on the natural sciences and useful arts,and the Missouri Botanical Garden Library at St. Louis is especiallyrich in monographs and floras.These are but a few of the many collections of world-wide signif-

icance that are in American libraries. The modern tendency in li-brary-making, both among private and public collectors, is "to con-centrate on some one field or portion of a field, rather than to scat-ter. For this reason a list by subjects, showing just where the ma-terial on certain topics may be found, is peculiarly valuable to theserious searcher after knowledge. The bulletin, "Special Collectionsin Libraries in the United States," was compiled for the Bureau ofEducation by W. Dawson Johnson and Isadora G. Mudge, of Col-umbia University, and has been printed for’free distribution.
