Geological Society of America
The Geological Society of America (or GSA) is a nonprofit organization dedicated to the advancement of the geosciences. The society was founded in New York in 1888 by Alexander Winchell, John J. Stevenson, Charles H. Hitchcock, John R. Proctor and Edward Orton and has been headquartered at 3300 Penrose Place, Boulder, Colorado, USA, since 1968. As of 2007, the society has over 21,000 members in more than 85 countries. The stated mission of GSA is "to advance the geosciences, to enhance the professional growth of its members, and to promote the geosciences in the service of humankind". Its main activities are sponsoring scientific meetings and publishing scientific literature, particularly the journals Geological Society of America Bulletin (commonly called "GSA Bulletin") and Geology. A more recent publication endeavor is the online-only science journal Geosphere. In February 2009, GSA began publishing Lithosphere. GSA's monthly news and science magazine, GSA Today, is open access online.
