The University publishes bulletins six times a month, so numbered that

the first two digits of the number show the year of issue; the last two

the position in the yearly series. (For example, No. 1701 is the first

bulletin of the year 1917.) These comprise the official publications of

the University, publications on humanistic and scientific subjects,

bulletins prepared by the Department of Extension and by the Bureau of

Municipal Research and Reference, and other bulletins of general

educational interest. With the exception of special numbers, any

bulletin will be sent to a citizen of Texas free on request. All

communications about University publications should be addressed to the

Chairman of the Publications Committee, University of Texas, Austin.
