In 1993, a Bristol bookseller auctioned off an untitled manuscript for an unpublished 1670s collection of Robin Hood ballads. This was called the Forresters Manuscript after the title of the first ballad.

Some ballads, such as Robin Hood and Queen Catherin and Robin Hoods Fishing, are longer and more complete than any other versions.

"New" ballads include "Robin Hood and the Bride" (a relative of the Alan a Dale story), "Robin Hood and the Old Wife" (a reworked version of Robin Hood and The Bishop), "Robin Hood and the Sheriffe" and "Robin Hood and the King" (using some concepts in other ballads.)

The book is available with an introduction and notes by Stephen Knight (a copy is currently resting on my lap).

Here's the link to it on Amazon.
