The drive to establish a county library in Crosby began in 1921. The first collection of 87 books arrived January 22, 1922.

In 1929, the Crosby community began a movement to acquire a building for the library. Mr. O.A. Reidland donated a 9 X 12 foot building, Mr. J. J. Orsag agreed to lend the library a lot and have the building moved to the site. Mr. Albert Nelson provided carpentry work and painting to get the building into shape. On January 5, 1930, the building opened. Mrs. Ada Anderson was the branch librarian. In 1931 there were 812 volumes in the collection with a circulation of 8,960. In 1933 the building was expanded to 12 x 18 feet and acquired a new roof, floor, shelving and window.

In 1956 the library moved to an air-conditioned office building. The Sorosis Club and local citizens assisted in the move and the community provided the furnishings. Mrs. Louise Reynolds was the librarian and stayed with the county until her retirement in October 1978. Joe Washburn became librarian until June 1979 when Nancy Stephens took over. In 1979, the collection was 4000 volumes with a circulation of 14,800.

In October 1979, the Crosby Newport Optimist Club began a drive to move and expand the branch. A Friend's group was organized in December 1979 and January 1980. The interest shown by the community led the Commissioners Court to approve rental of a larger space for the library. A site was found at 514 Church St. The Friends of the Crosby Library purchased a circulation desk, picture book shelf, table and chairs and a 16mm film projector with funds from their membership drive and book sales. The Harris County Library system bought shelving, an outside book drop and other furniture. The formal opening was on April 12, 1980. The library was open 32 hours a week and provided a storytime

In July 1980, Commissioners Court approved two full-time employees, allowing the library to be open 41 hours a week. Nieves Lehmann transferred from Stratford Branch in October 1980 and became the Assistant Librarian. The collection was 4900 volumes with a circulation of 26,700. The new Crosby Library had a groundbreaking ceremony on July 31, 1986. The library was more than five times the size of the old building on Church Street and the staff increased from two to five employees.

The dedication for the new library was October 8, 1987. County Commissioner Jim Fonteno handed the key to Maxine Hilburn, librarian. A live oak tree was planted to honor librarian Bruce Hancey for his efforts at getting the library relocated to the new building.

In November 1989, Crosby resident Hazel Clibourn donated a living Christmas tree to the library. The tree was planted near the front doors of the library and continues to grow to this day. The Crosby Library celebrated it's 10 year anniversary October 1997. The Friends of the Library held a reception for the community. A crepe myrtle was planted beside the library in honor of the event. A Bradford pear tree was planted in May 1999 in memory of Friend of the Library, Helen Steinbeck.
