Bulletin - Illinois State Geological Survey
Bulletins, the ISGS’s seminal publication series, are comprehensive reports and reference works of enduring scientific significance that communicate new data and original ideas to other earth scientists. Bulletins are typically the culmination of a large body of work, some parts of which may previously have been published in geologic maps, circulars, journal articles, or other publications. These reports include results of resource studies and of geologic, hydrologic, or topographic investigations, which often take several years to complete. A Bulletin may include collections of related short papers addressing different aspects of a single scientific topic, issued either as individual chapters or as a single volume. These reports undergo rigorous internal and external peer review, editing, and revision to ensure accuracy and a high level of comprehension. The first Bulletin was published in 1906.
