"Come on, Jaina. Leave that stuff alone."
"But I wanted to get my book chips. I think they're in this bag."
"You're not going to have any chance to read until after takeoff anyway."
Luke Skywalker and Jaina Solo[src]

A book chip, or bookchip, was a device used to read. In 18 ABY, Jaina and Anakin Solo brought book chips on their trip to Corellia with their family.
