The state of California is planning to phase out textbooks in favour of internet learning.
Governor Arnold Schwarzenegger says teaching pupils via online tools will help them keep more up to date on course materials, and learn new ways of using technology. Digital editions are updated often and easily, he said.
The plan will start at the beginning of the next school year in August, when high school pupils in maths and science classes will start to learn from online texts.
The state is facing a budget deficit of $23.4bn and has cut funding for any contract signed after March 1st.
Suspicions have been raised that the move is aimed at cutting expenditure, with $350m spent on textbooks last year.
