Most of the stories were derived by Longfellow from his wide reading — many of them from the legends of continental Europe, a few from American sources. The best known inclusion is the previously-published poem "Paul Revere's Ride". It also includes "The Saga of King Olaf", a poem which Longfellow started writing as early as 1856, making it the oldest in the collection. While assembling the collection, he originally intended to use a poem called "Galgano", a translation he had made in 1853 from a work by Italian poet Niccolò di Giovanni Fiorentino, as the student's tale; it was replaced with "The Falcon of Ser Federigo", translated from "The Decameron". Fields was heavily involved with the preparation of the book, particularly in the selection of individual titles for the poems, as well as for the title of the book itself, and suggestions for rhyming words. When the book was announced for publication, it was the poet's friend Charles Sumner who finally persuaded him to change the title from "The Sudbury Tales" to "Tales of a Wayside Inn".
