Our mission is to collect, preserve, organize, and make accessible materials that document the history of San Antonio and South Central Texas with an emphasis on historic buildings, objects, places, and customs. The library is open to the public, as well as to the members and staff of the Conservation Society.

Virtual Exhibits

These online exhibits feature historic photos, documents, and maps from our growing digital collections and provide fascinating glimpses into various aspects of San Antonio history.

Portal to Texas History

The library is a proud partner of the Portal to Texas History, operated by the University of North Texas.  The Portal provides free online access to Texas historical materials from libraries and museums across the state.  The Ernst Raba Collection is the first of our photographic collections to be featured in the Portal.  We will be adding images until all 246 in the collection are posted!
