Open-File Reports

Open-file reports are used as a limited-use series to be used for the dissemination of information that must be released immediately to fill an urgent public need or information that is preliminary or provisional in nature and will be superseded by a final product in another publication series, such as other USGS series or an outside publication. Open-file reports are not intended to be of lasting scientific importance.
