publications were carefully checked by means of circulars and a 

 reduction of approximately 29 per cent in the total number of 

 addresses was effected. Still further economies were secured by 

 issuing the annual report in paper covers instead of bound in cloth 

 as heretofore and by discontinuing the bound volumes of the pro- 

 ceedings which, beginning with volume 66, will be published only 

 in the form of separate pamphlets. The savings effected through 

 the foregoing changes will approximate $2,000. 



The editorial office, besides supervising the printing of the publica- 

 tions, has charge also of all miscellaneous printing and binding for 

 the Museum, in which connection approximately 510,000 forms, 

 labels, and other items were printed and 256 books were bound. 



The complete distribution of the Museum volumes and separates to 

 libraries and individuals on the regular mailing lists aggregated 

 90,303 copies while in addition 14,293 copies of publications issued 

 during this and previous years were supplied in response to special 

 requests. 



Eesearches based wholly or in part on the collections in the 

 National Museum resulted in many publications by members of the 

 Museum staff and others issued by other bureaus of the Govern- 

 ment and by outside institutions, all of which are cited in the bibli- 

 ography at the end of this report. 



LIBEAET. 



Because of the limited funds assigned for the purpose the Na- 

 tional Museum is able to purchase very few books so that the 

 accessions catalogued during the year in the library, which num- 

 bered 1,457 volumes and 1,894 pamphlets, were obtained mainly by 

 exchange. Careful check on publications of institutions with which 

 exchange relations have been established is maintained that the files 

 of such papers may be complete. The library is greatly indebted 

 to many private individuals, particularly members of the Museum 

 staff, for numerous donations of publications. 



In addition to the publications received and catalogued, a very 

 large number of works were received too late to be put through the 

 cataloguing routine, among which may be j)articularly mentioned 

 the entomological library of the late Col. Thomas Lincoln Casey, 

 numbering approximately 4,500 books and pamplilets, mostly relat- 

 ing to Coleoptera, which was bequeathed to the Museum by Colonel 

 Casey, and 800 books and pamphlets relating to the science ol numis- 

 matics which were transferred by the Treasury Department. Men- 

 tion may be made here also of the , Lacoe collection of books and 

 pamphlets, approximately 2,000 of each, and of the Edgar E. Teller 

 collection of about 500 volumes and 500 pamphlets which still await 

 cataloguing.
