The Dilys Award was presented every year from 1992 to 2014 by the Independent Mystery Booksellers Association. It was given to the mystery title of the year which the member booksellers have most enjoyed selling. The Independent Mystery Booksellers Association is an association of retail businesses that are either wholly or substantially devoted to the sale of mystery books. The Dilys award is named after Dilys Winn, who founded the first specialty bookseller of mystery books in the United States. Source: Wikipedia (en)
