The original library was created after a successful referendum in 1966. Originally located in a storefront, the library increased to four storefronts between the years of 1969 and 1975 and increased the number of hours it was open to 66 hours per week. Not long after that the library converted to a district library and began offering services to a large part of Hanover Park. One year later construction began for a new building located on Park Avenue. In 1980 the library became a government depository for federal and state documents. In 1991 a modular unit became the Branch in Hanover Park. In 2006 it was named the Sonya Crawshaw Branch in honor of the late President of Hanover Park.
