This booklet was likely printed in 1969 in celebration of Southern Illinois University's centennial celebration. It provides a brief history of the growth of campus with short histories of the campus buildings up to circa 1969. It also includes brief descriptions on the Vocational Technical Institute and Outdoor Laboratory at Little Grassy Lake. The university called the period from 1969-1974 the centennial years because it was chartered in 1869 and held its first classes in 1874.
