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.
The songs are listed in the index by accession number, rather than (for example) by subject matter or in order of importance. Some well-known songs have low Roud numbers (for example, many of the Child Ballads); but others have high ones.
