A renaissance in Illinois history scholarship has sparked renewed interest in the Prairie State's storied past. Students, meanwhile, continue to pursue coursework in Illinois history to fulfill degree requirements and for their own edification.   This Common Threads collection offers important articles from the Journal of the Illinois State Historical Society. Organized as an approachable survey of state history, the book offers chapters that cover the colonial era, early statehood, the Civil War years, the Gilded Age and Progressive eras, World War II, and postwar Illinois. The essays reflect the wide range of experiences lived by Illinoisans engaging in causes like temperance and women's struggle for a shorter workday; facing challenges that range from the rise of street gangs to Decatur's urban decline; and navigating historic issues like the 1822-24 constitutional crisis and the Alton School Case.   Contributors: Roger Biles, Lilia Fernandez, Paul Finkelman, Raymond E.
