The Des Moines Public Library began as the Des Moines Library Association in 1866 in the basement of a Methodist church. Early on, the library was supported by contributions and public charity. It started with nearly 2,300 books and a few periodicals. In 1882, it was decided to turn the library over to the city to become a free public library. The city purchased property at 100 Locust Street for the main library in 1898 for $35,000. The library opened in October 1903, and the Main Library branch remained at 100 Locust Street for more than 100 years.

In 1938, the library became the birthplace of the Library Bill of Rights under director Forrest Spaulding. The bill is still in use today by the American Library Association to ensure diversity of viewpoints in all library materials.

Through the years, the library became a cornerstone for the Des Moines community. In 1937, the Boys and Girls Department opened on the ground floor. During the 1930s, local artist Harry Donald Jones began painting a mural on the ground floor as a Works Progress Administration (WPA) project. The mural, called "The Social History of Des Moines," traced the growth of Des Moines from prehistoric times to present days. In the 1950s, the library developed a music department that featured a large collection of circulating vinyl records, a listening room with piano and record player, and a series of free concerts of recorded music presented weekly in the library's auditorium.

Beginning in the 1960s, the library began consolidating several of the small branches into larger regional branches. This began with the West Side Branch opening in 1965 (later renamed the Franklin Avenue branch). The new East Side Library opened in 1970, and the South Side Library was built in 1977. This was followed by the North Side Library in 1983 and the Forest Avenue Library in 1992. These regional branches helped increase the services available to patrons while remaining neighborhood-based at heart.

In April 2006, a new Central Library opened at 1000 Grand Avenue. The new building was designed by London architect David Chipperfield to serve the library's growing collection and the technology needs of 21st century users. The previous Central Library (located at 100 Locust) is now the home of the World Food Prize.

The Library Foundation of Des Moines was founded in 1998 to support the resources and services of the library through fundraising and advocacy. The Foundation supports programs that benefit the Des Moines community and promote the library's resources. With help from donors, foundations and corporations, the Foundation helps support the Des Moines Public Library.
