The Libretexts is an OER collaborative platform to enable dissemination and evaluation of new education developments and approaches, with an emphasis on data driven assessment of student learning and performance via a freely available online infrastructure. The Libretexts was recently expanded to 12 pseudo –independently operating and interwoven libraries covering 12 academic fields to function as a central platform for the construction and implementation of post-secondary OER textbooks. Since its inception eight years ago, the LibreTexts has been exponentially growing and is the most visited chemistry website in the world with 30 other participating campuses and over $3M of student textbook savings to date. This presentation addresses our recently expansion efforts and the next next-gen phase of development to integrate emerging education technologies into the content.
