- The library has always been of great importance in Seguin.
- The first Seguin Library was located at the Municipal Building on North Camp. In 1930, during the depression, Mayor Max Starcke gave permission to place a bookcase "in a city office for a lending library."
- Later on, when the new Municipal Building was being built a request was made that a room be set aside for the library. The facilities for the community's first library were as humble as the founding of Seguin. "The room was a 14 1/2 by 21 foot room in the Municipal building.
- In 1964 a contract was awarded to construct the Seguin-Guadalupe County Library on the donated Bauer land.
- Within 20 years the library needed to be expanded. Construction and renovation began in the fall of 1985 and was completed in July 1986. The size of the library was increased to 15,000 square feet.
- On November 5, 2013 Seguin voter's approved Proposition #1 of the City of Seguin Bond Elections. The proposition called for $14.8 million in bonds to cover estimated costs for property, construction, collection materials, furniture and signage, technology and computers for a new library.
- The groundbreaking ceremony was on April 23, 2015 at the new location 313 West Nolte Street.
- The new library opened on September 8, 2016. The new library is over 43,000 square feet.
