The Castroville Public Library began operation in 1963, and was the first public library in Medina County.  Credit for making a dream become a reality goes to the local Home Demonstration Club.  From a very small beginning, a full service library is now available.

While book circulation is the most active service, magazines, videos and audio tapes are available.  New computers equipped with CD-ROM drives and programs such as Microsoft Word and Excel are available for use.  The computers are also on-line and linked to the Colorado Alliance of Research Libraries for further research.  As a member of the Alamo Area Library system, the library takes part in 3 regular rotating circuits which include the books on Tape, Spanish language and Large Print Materials.  This system also allows them to "borrow" books, audio and video cassettes.  There is also a genealogy section which consists of an extensive collection of information on Medina County residents.  The Oral History Collection provides an invaluable source of unwritten history.

Tapes may be listened to anytime during regular library hours.  Some of the tapes have been transcribed.  Also included in available materials is a large collection on the past, present and future of Texas and Texans.

The original library, which had been in use for 25 years, became too small to meet present-day needs.  In April 1985, the Castroville Area Chamber of Commerce purchased two lots from the Sisters of Divine Providence for a Library/Chamber of Commerce building. The Chamber of Commerce is currently located at the Steinbach House.
