Open File Series - Illinois State Geological Survey

 
This series was begun in 1979 as a way for ISGS authors to make publications of time-sensitive topics available quickly. Contents of these editions may include technical or nontechnical reports (including contract/grant reports), maps, cross sections, and other materials (e.g., preliminary results or supporting documentation for some formal publication) that need timely release but not wide circulation.
