This is awesome. Congratulations! It should be thrown in the face of the textbook publishing industry that still charges $100+ dollars for yearly reprints of paper bricks.
This is what the textbooks should be in the 21st century! Outstanding work and hopefully it will inspire new generation of academics to take the outdated textbook publishing monopolies out of the loop in the future.
