Free, open-license university textbooks and reference books for BS degree programs taught at universities across Pakistan. This section follows the HEC curriculum and currently focuses on Computer Science — with subjects such as Programming, Data Structures, Database Systems and Operating Systems — with more disciplines being added.All books here are shared for educational purposes under free or open licenses, so BS students can access core course material without cost. Where a book is available only from its official source, we link directly to the publisher.
