This is a list of songs by their Roud Folk Song Index number; the full catalogue can also be found on the Vaughan Williams Memorial Library website. Some publishers have added Roud numbers to books and liner notes, as has also been done with Child Ballad numbers and Laws numbers. This list (like the article List of the Child Ballads) also serves as a link to articles about the songs, which may use a very different song title. Some of the songs were also included in the collection Jacobite Reliques by Scottish poet and novelist James Hogg.
