The Sioux City Free Public Library is a historic building located in Sioux City, Iowa, United States. The library was located in a section of the Municipal Building, no longer extant, between 1892 and 1913. It had outgrown the space when the Library Board contacted Andrew Carnegie in 1910 about providing the funding for a new library building. Their request was initially turned down. They chose to work with New York City architect Edward L. Tilton, an architect preferred by Carnegie, in place of local architect William L. Steele who was working with the board previously. Local resident George Murphy donated the property for the new building. Meanwhile, Tilton designed the two-story brick Renaissance Revival building. On April 8, 1911, Carnegie approved the project and donated $75,000 for the building's construction. The new building was dedicated on March 6, 1913, and it is considered "an excellent early twentieth century example of the architectural development of library planning and design." It was Tilton's only building in Iowa. Plans were made to enlarge the building in 1938, but the bond issue failed. The library remained in its cramped quarters until 1989 when it moved into a former bank building downtown. Ownership of the Carnegie building was transferred to a group of investors in 1996 who transformed it into apartments. It was listed on the National Register of Historic Places the following year.

Mary Elizabeth Day Nursery, also known as Mary Elizabeth Day Care Center, is a historic building located in Sioux City, Iowa, United States. This is the oldest child day care facility in the state of Iowa, and the state's second-oldest preschool. The Sioux City Day Nursery was established in 1914 by the Wall Street Mission, a local settlement house operated by the Methodist Episcopal Church. They moved here in 1926, which is the first building designed as a day nursery in Iowa. The two-story brick Renaissance Revival building was designed by local architect Jurgen A. Raven, and built by The Lytle Company, a Sioux City construction firm. Parents were responsible for paying for at least part of their children's care, but it was also subsidized by religious institutions, private associations, and individuals. During the Great Depression, both the federal and state governments began to fund and license child care. The Works Progress Administration was involved in the 1930s. A garage and playhouse designed by Sioux City architect Knute E. Westerlind was built in 1940, and it is part of the historic designation. The facility was renamed the Mary Elizabeth Day Care Center in 1990. The building was listed on the National Register of Historic Places in 1997.

A few other businesses occupied the space until Sioux City Tent and Awning was located here from 1937 to 1941. The following year Lewis System moved in and remained until 1969. The second floor was converted into apartments about 1950. The Lewis System, Inc. was established in 1919 and incorporated in 1922 by Harry Lewis, who grew up in St. Louis and was in the United States Army before he became a railroad detective and moved to Sioux City. By 1930 the company grew to 111 employees and had offices in Sioux Falls, South Dakota, Omaha, Nebraska, Chicago, and Kansas City, Missouri. A large portion of their business was in retail crime, but they also provided security guards for business firms, security checks, and security alarms. After Harry's brother Paul joined him in the late 1930s they added the armored car division. That division opened offices in Des Moines, Waterloo, Fort Dodge, and Cedar Rapids in Iowa and in Sioux Falls. Harry Lewis served as the company president until his death in 1951, and Paul took over from him and continued until his death in 1957. The company was sold to Samartick and Company of Omaha and they operated the business here until 1969. Wells Fargo Armored Car Service took over the building in 1970 and remained here until 1996.

The Motor Mart Building, also known as the Commerce Building, is a historic building located in Sioux City, Iowa, United States. It was built by Ralph A. Bennett, who was the owner of Bennett Auto Supply Company. The structure was designed in the style of the Chicago school by E.J. Henriques of the C.F.

The Sioux City Grain Exchange (SCGX) was a cash commodity market in Sioux City, Iowa that primarily traded corn, wheat, oat, and soybean. It was established in 1907 as the Sioux City Board of Trade, named the "fastest growing grain market in the world" in 1929, and among the largest exchanges in the world by the 1970s; transacting over 100 million bushels annually (valued at $1 billion as of 2018). It served the Corn Belt (primarily Iowa, Nebraska, South Dakota, and Minnesota) and primarily competed against the Chicago Mercantile Exchange, Minneapolis Grain Exchange and Kansas City Board of Trade. SCGX's rise and decline was driven by barge navigation of the Missouri River and mirrored the Sioux City Livestock Exchange (Sioux City Stockyards), the largest in the world during the 1970s. Both were co-founded by Vermont banker Fred L. Eaton.
