The Mobile Bookstore Society is an online community for people who sell books from trolleys, vans, trailers, campers, kiosks and book trucks. It exists so mobile booksellers can share what they know instead of working through the same problems alone.

It was started by Dani Scovel, founder of Curbside Books, a mobile bookstore run from a vintage trolley named Trolley Parton in Boise, Idaho. She wanted a place to ask real questions and get real answers, and the community now has over 150 members.
