LIBRARY. 441 



in the Bureau, the catalogues and otlier equipment, it is still necessary 

 to carry on the work in the locations of the former separate libraries, 

 namely, room 247, second floor, and room 425, fourth floor of labora- 

 tory A. The reorganization of the work will undoubtedly give the 

 Bureau better library service, but until all the work can be brought 

 together in one convenient location and another assistant appointed 

 it will ])e impossible to give the new arrangement a fair trial. Some 

 3'ears ago the Bureau started a card index of veterinary literature. 

 This grew rapidly for a few years, but recently its growth has been 

 slow on account of lack of assistance to keep it fully up to date. It 

 now comprises approximately 180, 000 cards. The possibilities 

 for usefulness to the Bureau and to scientific workers throughout the 

 country are large, and it is hoped that sufficient assistance will be 

 available to revise the catalogue and to bring up to date certain 

 subjects which have been somewhat neglected. 



'There was no outstanding feature in the work of the library of the 

 Bureau of Biological Survey other than a further condensation of 

 space available for its accommodation, about 500 books have been 

 returned to the main library for filing, bringing down the collection 

 to about the minimum possible. Since the Bureau is in close prox- 

 imity to the main librar\', it being on the floor above, the library duties 

 connected with this branch library are somewhat incidental and con- 

 sume a small part of the time of the one in charge, his principal duties 

 being editorial in character. 



The libraries of the Bureau of Crop Estinates and the Bureau of 

 Entomology both call attention to the crowded condition of their 

 shelves, which has made it necessary for them to send more of their 

 collections to the main library for filing. Still further and more radi- 

 cal reductions in their collections will be necessary unless more space 

 is made available for these libraries. 



A change in the location of the Office of Farm Management library 

 took place during the year, the offi:"e having been moved from 224 

 Twelfth Street, SW., to the corner of Fourteenth and B Streets, SW. 

 The change was beneficial, since the library now has more space and 

 more light. There is a further advantage in the fact that the building 

 in which it is located is next to the one in which the main library is 

 located, thus making it more accessible. 



The work of the Forest Service library was carried on along the 

 lines of previous years and no new work was be^un. The records in 

 connection with the purchase of books for the "field libraries" of the 

 Forest Service, tiiat is, libraries connected with offices, stations, and 

 laboratories of the service outside of Washington, are handled by the 

 librarian of the Service. There are 162 of these field libraries. Of 

 these, 149 are on National F'orosts, 6 in the District Foresters' ofiices, 

 6 at the Experiment Stations, and one at the Forest Products Labo- 

 ratory, Madison. About S2,000 was spent by the Service last year for 

 these libraries, aside from the Forest Products Laboratory, which pur- 

 chases its own books. 



The records connected with the purchase of books and periodicals 

 for the field libraries of other bureaus are also for the most part kept 

 by the bureau libraries. Varying amounts are spent by eacn bureau 

 for su(;h purposes. 



The outstanding feature of the Bureau of Markets library during 

 the year was the clear differentiation of the library and the editoriiil
