[4] Their fourth branch, The Nelson and Tracy Wolff BiblioTech EDU, opened in December 2022 near downtown San Antonio and serves both residents of Bexar County as well as students on the shared campus of Fox Tech, Cast Tech and ALA.[5] The library lends e-readers and digital content rather than physical media.

Members with a library card can also download the cloudLibrary app to read eBooks from their personal device (iOS, Android, Windows).
