We're not talking about rooms that are just full of books: we're talking about bookshops in barns, disused factories, converted churches and underground car parks. Meet Sarah and her Book Barge sailing across the sea to France; meet Sebastien, in Mongolia, who sells books to herders of the Altai mountains; meet the bookshop in Canada that's invented the world's first antiquarian book vending machine. Campbell examines the history of books, talks to authors about their favourite places, and looks at over three hundred weirdly wonderful bookshops.
