A very useful publication is the "Guide to United States Government Publications," published by the U.S. Bureau of Education as Bulletin, 1918, No. 2. It not only describes the publications of each department of government, but also the organization and work of each department and its subdivisions. (Government Printing Office, 20 cents.)
More recent and equally useful is "The Federal Executive
Departments as Sources of Information for Libraries," also
published by the Bureau of Education, Bulletin, 1919, No. 74
(Government Printing Office, 25 cents). The work of each
Department and its subdivisions is described in some detail.
