The publications of the United States Geological Survey are issued in accordance with the statute 
approved Mareh 3, 1879, which declares that— 
“The publications of the Geological Survey shall consist of the annual report of operations, geo- 
logical and economic maps illustrating the resources and classification of the lands, and reports upon 
general and economie geology and paleontology. The annual report of operations of the Geological 
Survey shall accompany the annual report of the Secretary of the Interior. All special memoirs and 
reports of said Survey shall be issued in uniform quarto series if deemed necessary by the Director, but 
otherwise in ordinary octavos. Three thousand copies of each shall be published for scientific exchanges 
and for sale at the price of publication; and all literary and cartographic materials received in exchange 
shall be the property of the United States and form a part of the library of the organization: And the 
money resulting from the sale of such publications shall be covered into the Treasury of the United 
States.” 
The following joint resolution, referring to all government publications, was passed by Congress 
July 7, 1882: 
“That whenever any document or report shall be ordered printed by Congress, there shall be 
printed, in addition to the number in each case stated, the ‘usual number’ (1,900) of copies for binding 
and distribution among those entitled to receive them.” 
Except in those cases in which an extra number of any publication has been supplied to the Sur- 
vey by special resolution of Congress or has been ordered by the Secretary of the Interior, this office 
has no copies for gratuitous distribution.
