LIBRARY. 



The library of the Bureau of Crop Estimates, which is a branch 

 of the library of the department, during the fiscal year received 

 approximately 300 foreign and 300 domestic periodicals containing 

 useful information regarding agricultural statistics. Of these peri- 

 odicals about 160 were monthly, 150 weekly, 48 daily, and the re- 

 mainder were issued at other periods. The total number of separate 

 copies of periodicals received was about 30,000. 



The books in the library comprise the agricultural reports of prac- 

 tically all countries issuing such reports; also a fairly complete col- 

 lection of the official reports of exports and imports for each for- 

 eign country. The collection of State reports on agriculture and 

 live stock is practically complete; also annual statistical reports of 

 commercial agencies, such as boards of trade, chambers of commerce, 

 cotton exchanges, etc. Efforts were made during the year to supply 

 what was lacking from this class of publications.
