442 -- Mineral Resources of Alaska Report on Progress of Investigations in 1909 by Alfred H. Brooks and Others, 1910

This collection contains publications from the United States Geological Survey and has been arranged into nine series.

Series 1 New Publication Lists and Publication Information includes annual lists of publications from the USGS beginning in 1971 through 1980. Starting in January 1981, publication lists were released monthly. Two volumes list all papers from 1893 through 1970. This series also contains two volumes of information for authors on the preparation of illustrations and maps.

Series 2 Professional Papers are comprehensive reports of wide and lasting interest and scientific importance, characterized by thoroughness of study and breadth of scientific or geographic coverage. Related papers addressing different aspects of a single scientific topic are sometimes included in the same booklet.

Series 3 Geological Survey Circulars are concise reports regarding geographic areas, specific issues or USGS programs. Circulars are meant to increase the understanding of a general audience, including politicians, university students, and scientists of other fields.

Series 4 Water Supply Papers include both extensive and concise reports on all topics of hydro resources including quality, recoverability, and use of water resources, statistical reports on streamflow, floods, groundwater levels, and water quality.

Series 5 Bulletins are reports of broad and lasting scientific importance but are much more narrow in scope than professional papers. Bulletins include short papers and the results of resource studies and geologic or topographic studies.

Series 6 Trace Elements Memorandum, Trace Elements Investigations, and Manhattan District Declassified Documents includes materials regarding elements of nuclear testing between the mid-1940s and 1966.

Series 7 Journal of Research are a bi-monthly publication of reports on geologic, hydrologic, topographic, and other technical subjects.

Series 8 Open-File Reports consist of information that needed to be released immediately. This is usually because the map or report is referenced as supporting documentation in another USGS publication.

Series 9 Maps and Miscellaneous Publications includes several different types of maps including Oil and Gas Investigations, Geophysical Investigations, Miscellaneous Field Studies, Miscellaneous Investigations/ Geologic Investigations, and topographic maps. Other publications found in this series include annual reports.
