The book was originally illustrated by Pauline Baynes and later by Roger Garland. The book, like the first edition of The Fellowship of the Ring, is presented as if it is an actual translation from the Red Book of Westmarch, and contains some background information on the world of Middle-earth that is not found elsewhere: e.g. the name of the tower at Dol Amroth and the names of the Seven Rivers of Gondor. There is some fictional background information about those poems, linking them to Hobbit folklore and literature and to their supposed writers, in some cases Sam Gamgee.
