 accompanying the publications of their respective bureaus and offices 

 has been continued. In addition, an assistant in the Bureau of 

 PLant Industry library has continued to revise all bibliographical lists 

 accompanying the papers for the Journal of Agricultural Research. 



The list of books and articles indexed by the Forest Service library 

 is still printed each month in American Forestry. The library has 

 also prepared during the year a number of special bibliographies on 

 forestry subjects, the longest being on the forest conservation move- 

 ment in the United States, and a list of Forest Service publications 

 issued up to November 15, 1915. 



In the Bureau of Entomology library a bibliography on insects as 

 food is being prepared and the index to articles on insects in depart- 

 ment publications continued. 



In the library of the Office of Grain Standardization a bibliog- 

 raphy on gluten and protein in wheat and wheat flour has been 

 revised and a bibliography on future trading, hedging, and specu- 

 lation in grain and cotton transactions prepared. 



In the Bureau of Chemistry library a compilation was made of 

 foreign laws requiring chemical and physical tests to be applied to 

 imported food products before entry into a country, and of those 

 requiring that imported food products be accompanied by certifi- 

 cation from the country of origin. A list of references was also 

 compiled to articles which have appeared during the past five years 

 on the importance of mineral or inorganic salts in the diet. 



In the States Relations Service library progress has been made 

 in bringing up to date a manuscript revision of the List of Publica- 

 tions of the State Experiment Stations. It is hoped that this work 

 may be printed. Under the assignment to the States Relations 

 Service of the administration of the Smith-Lever Act, relating to 

 cooperative agricultural extension work, the library of the Service 

 began the collection of the extension publications of the institu- 

 tions cooperating with the United States Department of Agriculture 

 under this act. A check list, on cards, of these publications is in 

 progress. 



In the Office of Farm Management library short lists on the 

 farmer's income, cost accounting, and the cost of crop production 

 were prepared. A bibliography on farm management in the United 

 States is in preparation. 



In the Office of Markets and Rural Organization a bibliography 

 on the marketing of farm products was prepared and issued in 

 multigraphed form. 



In the main library work was continued on the index to the State 

 agricultural reports. About one-third of the reports have been 

 indexed. Numerous bibliographical lists varying in length from 10 

 to 55 items were prepared in answer to requests received in corre- 

 spondence. The most extensive list was on the subject of farm 

 tenancy. During the past year the library has also received an 

 increased number of requests for the verification of bibliographical 

 references. 



Work has been continued on the index and bibliography of the 

 literature of maize, a project of the Office of Crop Acclimatization in 

 the Bureau of Plant Industry, with which the library is cooperating. 

 The index now contains approximately 18,000 entries.
