By 1937, the garage became a Ford sales and service dealership, and a combination City Hall and volunteer Fire Department was built on the western half of the lot.

In 1962 the Round Rock Ladies Home Demonstration Club decided that the city needed a library.

Then they bought the old Ford Motor Company building on the corner of East Main Street at Sheppard, where the present library stands.

The work on the showroom was done by a Round Rock High School building and trade class and by local craftsmen.

Prior to the cities $4.2 million purchase of the property that the new library would be built on, a bar, Cozy Corner, had operated for several decades.

WCGS owns a collection of local genealogical and historical materials that are housed and cataloged by the Library.

Both organizations contribute to the upkeep and expansion of the collection, and both provide educational research seminars at the Library.
