Do the contestants on Jeapardy get study materials to review?

Your husband is right. A few years ago on a show (I can't remember which one),the host asked if they were given material to study from and the guy said yes.Not the answers but books on the subjects they were going to answer questions about like history,etc.

I remember during a show alex was asked during a commercial break if the contestants had any type of coaching or study material. He said no, they actually had to know the answers. Otherwise, there could be cheating.
