World Book Day 2015 Gallery
Our booksellers at Waterstones Exeter posed the question: what do you call a gathering of Wallys?
While at Waterstones Salisbury, someone was reading an informative new book...
Also in Salisbury, The Very Hungry Caterpillar was counting down the minutes to her lunch!
Elsewhere, The Cat in the Hat went to visit Waterstones Newcastle.
And a gorilla joined in the fun at Waterstones Gower Street.
Lots of our younger readers also joined in the fun on World Book Day. Lily dressed up as a scarecrow, inspired by The Wizard of Oz. - Photo by @amylouisex90
