Textbooks are going to remain a key part of learning. They just need to go digital, become more interactive and they need more analytics.

Using a service such as Chegg.com, students can save on average more than $600 a year when they rent textbooks over purchasing them.

Parents are telling other parents that you can save a lot of money renting. Forever they've been looking for a solution to higher textbook prices.

Students today need experience to get a job, and they need a job to get experience. The Chegg Champion program provides students with a real-world working experience that actually offers financial rewards.

The sea change that has come is the information age. We don't have to just read The New York Times anymore. We can pull up something on the Internet and get any news that we like.

The Internet has made us richer, freer, connected and informed in ways its founders could not have dreamt of. It has also become a vector of attack, espionage, crime and harm.
