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. NOTE: The following Open File Series numbers were never used: 1990-2e, 1990-2h, 1990-6, 1991-6, 1996-8, 1999-2, 1999-3, 1999-4, 2004-1, 2004-3, 2004-4.
