It might be hard to imagine school with out them, but kids in the American state of California could soon be ditching their text books for good.
State Governor Arnold Schwarzenegger has announced plans to go high-tech and swap books for online learning aids.
He reckons the plan will help kids keep up-to-date as digital books will always contain the latest information.
Another big reason is that the state will save loads of cash because they won't have to keep buying new books.
Governor Schwarzenegger told journalists in America: "The textbooks are outdated as far as I'm concerned.
"There's no reason our schools should have our pupils lug around these... heavy and expensive text books."
Some online textbooks will be available for students from the beginning of the next school year.
