 Nominees were originally limited to just books at the Frankfurt Book Fair, but this was extended to submissions sent in by "The Bookseller" magazine's traditional readership of librarians, publishers, and booksellers in order to decrease the risk of no award being given.In 2009, submissions could be sent to either Bent's or "The Bookseller's" Twitter accounts.People cannot nominate their own works, nor can they select books they publish themselves.
