The Booth Library Postcard Collection has as its focus the rich history of Illinois communities. Of particular note, strengths include:
Education in Illinois. The collection is especially rich in both interior and exterior views of buildings for schools, institutes, colleges, and universities. Additionally, photographs of students and teachers are included when available.
Libraries in Illinois. This collection was developed in conjunction with the Art and Architecture in Illinois Libraries project resident at Booth Library. Funded by the LSTA program of the Illinois State Library in 2006 and 2009 and by Eastern Illinois University, these postcards illustrate the history of libraries across the state. Additionally, library images from other states and nations are included when available.
