The Freeman Branch library first opened on November 1, 1964 and moved to its current location in the Harris County multipurpose annex in Clear Lake on July 13, 1976. The Freeman Library has been serving the Clear Lake area for 36 years. The Freeman Branch was named in honor of Captain Theodore C. Freeman, the first astronaut to lose his life in the U. S. space program.
A new joint facility between Harris County and the City of Houston opened on June 8, 2004 and is approximately 42,000 square feet.

With strong support from area families and the business community, the Friends of the Freeman Library raise $80,000 each year to purchase books, fund special children's programs, and upgrade library equipment and furnishings. Fundraising efforts, which include a bookstore in the library open most hours the library is open, an annual membership drive, and the "Books Alive Week," have financed many "extras" that enrich the quality of library service at the Freeman Library.
