The mission of the Society shall be to research, collect care for, exhibit, and interpret items that illustrate the history of Greene County from settlement to the present time, and place it in the context of the history of the State of Illinois. The Society shall assist in historical and genealogical research for educational and patriotic purposes; provide for the preservation of such material and its accessibility to all who wish to examine or study it; and shall encourage the preservation of historic buildings, monuments, and markers. The Society shall disseminate historical information by publicizing such material in newspapers or otherwise, by developing educational programs, and by operating a museum for the benefit of the public.

The Society may receive and hold gifts and devises of real and personal estate from any source for the benefit of the Society and may dispose of any real estate, chattel, and personal property not needed, and use solely for the purpose of the Society any funds derived there from, or from gifts generally, and do all things incident to the perpetuation of the Society. All of the foregoing is for carrying on the work of the Society for educational, patriotic, and historical purposes as provided in Section 501(c) (3) of the Internal Revenue Code of 1954.

The Society’s mission shall guide all efforts, including research, collections, exhibits, public programs, and sponsorship of earned income activities.
