B - Bulletin
This series is comprised of significant data and interpretations of lasting scientific interest but generally narrower in scope than Professional Papers. Includes collections of related papers addressing different aspects of a single scientific topic, either issued as individual chapters or as a single volume; proceedings and abstracts for USGS-sponsored meetings; some field trip guidebooks and road logs; and general manuals.
C - Circular
A wide variety of topics covered concisely and clearly to provide a synthesis of understanding about processes, geographic areas, issues, or USGS programs. A Circular is aimed at enhancing knowledge and understanding among general audiences, decision makers, university students, and scientists in related fields.
DDS - Digital Data Series
The Data Series is intended for release of basic data sets, databases, and multimedia or motion graphics. This series can be used for videos, computer programs, and collections of digital photographs.
FS - Fact Sheet
A wide variety of topics covered concisely and clearly; focus is on USGS science, programs, projects, and data and how they address issues of public interest. This series is not used to release new scientific data or information that has not been published elsewhere. May be used to summarize or publicize results of previously published studies and their implications. May be used to release new information about USGS programs and products.
GP - Geophysical Investigations Maps
Maps on topographic or planimetric bases; various scales; show results of surveys using geophysical techniques, such as gravity, magnetic, seismic, or radioactivity, which reflect subsurface structures that are of economic or geologic significance. Many maps are correlated with the geology.
GQ - Geologic Quadrangle Maps
Multicolor geologic maps on topographic bases in 7 1/2- or 15-minute quadrangle units; scales mainly 1:24,000 or 1:62,500; show bedrock, surficial, or engineering geology. Maps are also accompanied by brief texts and some by structure and columnar sections.
HA - Hydrologic Investigations Atlases
Multicolored or black and white maps on topographic or planimetric bases presenting a wide range of geohydrologic data; both regular and irregular areas.
HU - Hydrologic Unit Map
Maps that delineate units which are basically hydrographic in nature and which are used by the U.S.G.S. in cataloging water data.
I - Miscellaneous Investigations
Maps on planimetric or topographic bases; regular and irregular areas; various scales; a wide variety of format and subject matter. The series includes 7 1/2-minute quadrangle photogeologic maps on planimetric bases that show geology as interpreted from aerial photographs. Series also includes planetary maps.
I - Geologic Investigations
In August 1996, the I-map series name was changed from Miscellaneous Investigations Series Maps to Geologic Investigations Series. All geologic maps approved for publication after August 1996 were published in the Geologic Investigations Series. The series definition remains the same.
MF - Miscellaneous Field Studies
Multicolor or black and white maps on topographic or planimetric bases; quadrangle or irregular areas; various scales. Pre-1971 maps show bedrock geology in relation to specific mining or mineral-deposit problems; the majority of post-1971 maps are preliminary black and white maps on various subjects such as environmental studies or wilderness mineral investigations.
MR - Mineral Investigations Resources Maps
Maps showing geographic distributions and grade of mineral resources on a regional basis.
OC - Oil and Gas Investigations Chart
Charts showing stratigraphic information for certain oil and gas fields and other areas having hydrocarbon potential.
OF - Open File Report: Technical Data Unit classification number
Open-File Reports were reclassified in 1975 from a consecutive numeric scheme to the current YY-## scheme. Follow the link above to browse these citations according to their original publication numbers.
OF - Open-File Report
Interpretive information that needs to be released immediately; maps and reports (and their supporting data) that need to be released as supporting documentation because they are referenced, discussed, or interpreted in another information product; preliminary findings (pending a final map or report); interim computer programs and user guides; bibliographies.
OM - Oil and Gas Investigations Map
Maps showing stratigraphic information for certain oil and gas fields and other areas having hydrocarbon potential.
P - Professional Paper
This is the Premier series of the USGS. It consists of comprehensive reports of wide and lasting interest and scientific importance, characterized by thoroughness of study and breadth of scientific or geographic coverage. The series may include collections of related papers addressing different aspects of a single scientific topic, either issued together under one cover or separately as chapters.
SIM - Scientific Investigations Map
Scientific Investigations Maps present the scientific results of studies as maps, charts, stratigraphic sections, or other large illustrations. The map sheet or pamphlet may include additional descriptive information, photographs, or other illustrations. The series also may include collections of related maps addressing different aspects of a single geographic area or scientific topic, issued separately, or as an atlas, issued collectively in book format. Series includes planetary maps.
SIR - Scientific Investigations Report
Scientific Investigations Reports contain significant data and interpretations of lasting scientific interest but are generally narrower in scope than Professional Papers. The series includes collections of related papers addressing different aspects of a single scientific topic, either issued as individual chapters or as a single volume; proceedings and abstracts for USGS-sponsored meetings; some field trip guidebooks and road logs; and general manuals.
