LIBEAPvY. 343 



. Tho table given in Appendix 1 s1io\ys tlie number of books wliicli 

 liave been bound during the last 10 years, and the number of periodi- 

 cals currently received. From this table it will be seen that the 

 number of books sent to the bindery last year was only slightly in 

 excess of the number sent to the bindery in 1909, though the number 

 bound in 1909 was, owing to certain handicaps that J'ear, 300 less 

 tliun tlie number bound in 1908. From 1909 to 1917 the number sent 

 to the bindery had through strenuous efforts been more than doubled, 

 biit this gain has been entirely wiped out in the last two years. On 

 tlie other hand, the number of current periodicals received has in- 

 creased 25 per cent since 1909. These figures sIioav conclusively the 

 argent lieecl for a greatly increased allotment for Library binding in 

 order that the current periodicals and other unbound publications 

 may be preserved and made available for convenient use. In order 

 to meet the Library's present needs the number of books bound 

 annually should not be less than 5,000 volumes. 



BIBLIOGRAPHY. 



No new bibliographical work of special importance was under- 

 taken in the main Library during the 3'ear on account of lack of 

 assistance and the consequent difficulty of keeping up to date eveii 

 the routine work of cataloging. A number of miscellaneous refer- 

 ence lists on various subjects were, however, compiled, largely in con- 

 nection Avith correspondence. The various bureau libraries also 

 furnished many lists on their special subjects in connection Avith 

 correspondence or the special demands of their bureaus. 



The librarian of the Bureau of Entomology in January, 1919, was 

 placed in charge of a large and important bibliographical undertak- 

 ing, namely, the planning and supervision of the index to the litera- 

 ture of American economic entomology, 1915 to 1919, inclusive, a 

 continuation of the index previously compiled in the bureau under 

 the direction of Mr. Xathan Banks, entomological assistant. Among 

 the brief reference lists prepared in the library of the Bureau of 

 Entomology were an address list of State entomologists and a list of 

 entomological societies and journals, Avith the prices of the journals 

 and the addresses of the editors. Short lists of the new publications 

 received by the Bureau of Entomology library Avere furnished for 

 the Monthly Letter of the bureau.
