Informal adult learning opportunities in Wyoming at the turn of the century were offered through popular lectures, newspaper articles, a traveling library, and the University of Wyoming's libraries and museums. Laramie City, one of the earliest towns to be established in Wyoming Territory, was home to a large concentration of formally educated individuals who played a prominent role in the informal education of Wyoming pioneers. In 1886, the University of Wyoming was established. Its faculty's contributions were especially noteworthy in regard to their efforts to ensure that the university library was open to the adult public and that its holdings contained books and journals of general interest and educational value. As important as the contributions of the library to promote informal adult education in Wyoming were the various campus museums established during the period. The museums were open for public visits and inquiries. Through the efforts of the university librarian, adults living in remote areas were able to obtain fictional and nonfictional reading materials by means of a traveling library in 1913. Starting in 1890, university faculty introduced a system of special lectures that were open to all townspeople. Local newspapers played an important role in the educational life of the state during this period. Faculty members wrote numerous popular scientific articles for the local newspapers of Wyoming.
