As members of SCELC (Statewide California Electronic Library Consortium), TCS Education System Libraries participate in the Open Textbook Network which supports the Open Textbook Library . This helps higher education institutions and systems advance the use of open textbooks and practices on their campuses. It employs a Train-the-Trainer model to educate and engage leaders at the system and campus levels. Each summer, OTN holds a Summer Institute to train leaders who bring back expertise and best practices.
