The mission of the Harris County Public Library System is to provide information and resources to enrich lives and strengthen communities through innovative services within and beyond our walls. Throughout its history, the Library has made information available in a variety of formats. The Library's computer system provides the opportunity to integrate electronic resources from the Internet linked information networks from around the world -- with the Library's other resources, enhancing the Library's existing collection size and depth.
The Library exercises discretion in the selection of materials for inclusion in its collection, including materials it makes available on the Internet. To help guide users to the best electronic content, the Library has created web pages designed for the general population, children, and teens. The Library’s staff is also available for assistance in using online resources.
