When the library opened in 1976, Aldine was a small, semi-rural community. It has seen considerable growth since then and the Aldine Branch Library has grown right along with it to serve the area's diverse and ever-changing population.

From book cars and wagons to fully air-conditioned vehicles with Internet access, trace the bookmobile program from the 1920s to the modern-day.

HCPL has been providing library service to the Katy area since 1921.  The community built its first freestanding library building in 1940 after nearly two decades of the library floating between homes and private businesses.  The current Katy Branch Library building opened in April 2003. 

The Tomball branch started in the 1920s in a post office.  The bookmobile later served the community until support grew, and a branch was built in 1962.  Now operating in partnership with the Lone Star College, the LSC-Tomball Community Library is one of the largest HCPL locations.

A dedicated group of Katy residents started a campaign in 1984 for a new branch to serve the increasing population in western Harris County.  Nine years later, the Maud Smith Marks Library opened.  The branch is named in honor of Maud Smith Marks, who ran a small HCPL station in Barker, Texas, during the 1920s and 1930s.

Stratford Branch Library has long been a resource for the Highlands community.  The first public library in the area opened in 1927 and was located in a storefront.  The first freestanding Highlands Library opened in 1937 with 375 square feet. In 1966 a new building opened, thanks to a donation from Highlands resident Anna Stratford.
