History of Pima County Public Library

The history of public libraries in Tucson and Pima County

Tucson’s first public library was founded in 1883 (see timeline below) and opened to the public in 1886 on the 2nd floor of Tucson's City Hall. This very early library was referred to as "Library Hall."

The first true library building in Tucson was partially funded by Andrew Carnegie as a part of his campaign to build public libraries across America in the late 19th century. Carnegie committed to paying up to $25,000 to build a new library on the condition that the City of Tucson supplied a building site and provided $2,000 per year to maintain the library. The Tucson Common Council made good on this deal by passing Resolution Number 20. This resolution earmarked $2,000 per year for library maintenance and designated a site for the library, a portion of "Military Plaza" now called Armory Park.

Architect Henry  Charles Trost was hired to build the new library, which was completed in June of 1901. The Carnegie Free Library, administered by the city of Tucson, was located at 200 South 6th Avenue (current home of the Tucson's Children Museum). Initially, the library did not include a children’s room. This area was added after funds were raised in 1924. The library began with 2,000 volumes in 1891 but had grown to over 60,000 in 1942.

A new 90,000 square foot facility opened downtown in May 1990. Today, this building is referred to as the Joel D. Valdez Main Library.

Name changes: On January 7, 1957, the name of the Carnegie Free Library was oficially changed to Tucson Public Library by the Tucson City Council. This name was changed to the Tucson-Pima Public Library in 1990 when Pima County became more involved in the library’s operations. When Pima County took administrative control of the library system in 2006, we became Pima County Public Library.

Were there other libraries before 1883? 

Early libraries existed in Arizona Territory but most were not freely available to all.

1883 "Library Hall," Tucson's first municipal public library approved on June 5 by Tucson Common Council, and 2nd floor of Tucson City Hall set aside for its sole use.
