Launched in 2010 by the Wyoming State Historical Society, WyoHistory.org, offers a rich collection of materials and educational resources dedicated to the history of Wyoming. At the heart of this collection is an extensive encyclopedia of the state's history, which features over 400 articles about a range of events and individuals from Wyoming state history, accompanied by images and a full reference list for those interested in further reading. These entries, penned by professional scholars and writers, provide nuanced insight and analysis of Wyoming history. For example, in an entry about an 1889 lynching in central Wyoming, Tom Rea (who serves as editor of the site) provides a lengthy and revealing explanation about how journalists-- and, subsequently, historians-- got the events of the day wrong for many years. Visitors are invited to explore by title or by location (via an interactive pin map). Another highlight of this collection is the Oral Histories collection of Wyoming residents involved in historic events. Finally, educators will find materials to use in the classroom via the Education tab.
