LIBRARY OF THE SURVEY. 
A well-equipped geological library is becoming a constantly increas- 
ing need in the doing of creditable work by the Survey. In 1904, the 
library consisted of less than a hundred reports and pamphlets, which had 
been sent in voluntarily by the surveys of other states and foreign coun- 
tries. These had accumulated during the preceding four years. No 
effort had been made to form a regular exchange list, because the Ohio 
‘Geological Survey had nothing remaining from former issues which could 
be offered in exchange. When a new series of bulletins was ready for 
‘issue it seemed a proper time to take up seriously the question of exchange 
lists and the accumulation of a library. 
The library of the Ohio State University, though not large, has been 
‘carefully selected, and has the nucleus of a good collection of books on 
geology. The geological library of the late Dr. Edward Orton was pre- 
‘served intact, and has been presented to the University. It was thought 
a highly desirable thing if the reports and pamphlets received by the - 
Survey in exchange for its own publications could also be deposited in 
the same place. 
The chief obstacle heretofore to the Survey forming a library and 
accumulating geological exchanges has been in the lack of a definite 
method of caring for the books and pamphlets when received. The lack 
of a fixed office increased this difficulty. This last obstacle being removed, 
the foregoing facts were presented to the seventy-sixth general assembly, 
which passed the following resolution:
