Help Using U.S. Collection at Mines

  • The Library Catalog contains records for approximately 75% of the federal government publications collections at the Arthur Lakes Library and should be used first to locate these items. 
  • Prospector (regional catalog) can also be used to find additional government publications that may or may not be in the Arthur Lakes Library - those not in the Library can be requested through Prospector.

How to Locate Physical U.S. Government Publications at Mines

The Government Publications collections are located on the 1st Floor of the Arthur Lakes Library.

The Federal/U.S. print collection uses the SuDoc classification system. This system is designed to place together all of those publications published by the same federal government agency. The initial letter or letters of the call number signify the government agency responsible for publishing that document. All letters and combinations of letters are used except for the letter Z. The letters X and Y are used for Congressional publications.

  • I =Department of the Interior

The numbers following the letter(s) indicate the sub-agency within the larger agency.

Sub-agencies within the Department of the Interior

  • I 19. = U.S. Geological Survey
  • I 28. = Bureau of Mines
  • I 29. = National Park Service

A period follows these numbers. THIS IS NOT A DECIMAL POINT. The number following the period needs to be read as a WHOLE NUMBER. This whole number designates the type of publication.

Selected types of publications within the U.S. Geological Survey

  • I 19.1: = U.S. Geological Survey Annual Reports
  • I 19.3: = U.S. Geological Survey Bulletins
  • I 19.16: = U.S. Geological Survey Professional Papers
  • I 19.76: = U.S. Geological Survey Open Files Reports

Sometimes there are related series to already existing series. In order to have these related series filed together, a slash is used to indicate the relationship.

Selected U.S. Geological Survey related publications

  • I 19.3: = U.S. Geological Survey Bulletins
  • I 19.3/3: = U.S. Geological Survey. Water Resources Bulletins

Following the colon, there can be letters and numbers which usually indicate the title of the document or a designation for a year (1989=989 in this system).

Filing of U.S. government publications

The key phrase when looking for U.S. government publications in our collection is the "nothing before something" rule. For example, Interior publications (I) would file before International Trade Commission publications (ITC). Another crucial item is that the period is NOT A DECIMAL POINT and the numbers following the period need to be read a whole numbers. Finally, when looking for publications which differ in their classification number after the colon, the rule is DATE before LETTER before NUMBER before WORD. However, this does not apply to parts, volumes, sections, or revisions of the same publication. Below is a list of properly ordered U.S. government publications.

  • I 1.98:T 68
  • I 1.98:T 68/decision
  • I 1.98:T 68/draft
  • I 19.1:989
  • I 19.1:991
  • I 19.2:M 86
  • I 19.2:M 86/980
  • I 19.2:M 86/2
  • I 19.2:M 86/2/990
  • I 19.3:1134
  • I 19.3/3:657
  • I 19.14:990
  • I 19.14/4:987/5
