A bookmobile or mobile library is a large vehicle designed for use as a library. They are designed to hold books on shelves so that when the vehicle is parked the books can be accessed by readers. They usually have sufficient space so that people can also sit and read books inside them.
So what do you do?
I'm a Bookmobile driver.
The vehicle driven by an individual who is offered every job they apply for. Especially used in instances of persons working in the performing arts who "book" several jobs in a row.
I'm taking the Bookmobile down to Steppenwolf today - wish me luck!
