Many Oklahoma Geological Survey documents are available for free download. In the search box below, you can search by type of publication as well as by keyword. In addition to its publications, the OGS maintains an extensive collection of open-file information mostly in the form of well records and unpublished reports and maps. The Publication Sales Office is also the contact point for OPIC-related activities.

The OGS Bulletin is a peer-reviewed scientific research journal with over 150 volumes published continuously from 1908 to present. The Bulletin represents our highest level of publication, equivalent to other major peer-reviewed science journals. Articles are peer-reviewed by at least three reviewers. Hard copies are available in many libraries around the country as part of an exchange agreement.
Guidebooks published by the Oklahoma Geological Survey range from general information to more rigorous scientifc study and in many cases are intended to accompany symposia or workshops. They typically include field trip stops with thorough descriptions and photos.
Oklahoma Geologic Quadrangles (OGQs) are geologic maps professionally drafted by the Oklahoma Geological Survey cartography group. OGQ maps are reviewed by internal or external geologists and are thoroughly edited. Starting in 1989, several geologic maps released as Open-File Reports were rereleased as OGQs in an effort to group similar publications together.
Oklahoma Geology Notes are periodical publications of the Oklahoma Geological Survey containing short scientific and technical articles, mineral and petroleum statistics, the Director's annual report, news items, abstracts, and, from 1955 through 1980, an annual bibliography of Oklahoma geology.

The Hopper was issued monthly from 1941 through 1955; publication was continued thereafter as Oklahoma Geology Notes with volume numbers successive. From volume 16 through volume 27 Oklahoma Geology Notes was published 10 times a year, under 12 issue numbers.
Peer-reviewed journal articles have been published by current or former OGS scientists in scholarly journals. Typically, these articles are evaluated by outside experts in the field who check for accuracy and assess the validity of the research methodology and procedures. Peer-reviewed journals will not publish articles that fail to meet defined standards, therefore peer-reviewed articles exemplify the best research practices in a field.
Special Publications are issued by the Oklahoma Geological Survey or by the OGS in cooperation with other agencies. Each is listed according to the year of publication and the order it was published. Gaps in the series occur when no Special Publications were issued that year, or when a publication is out of print. Historically, many Special Publications were summaries of research conducted based on funding from a grant.
