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.

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.
