It was the original story of Star Wars, in the very early drafts. It was also named as The Son of the Sun at one point, but the story was alot different. George Lucas originally considered doing the beginning of Star Wars very different where you wouldve seen a child wookiee crying and its mother coming to comfort it--- and from a self it would pick up "The Journal of the Whills" and open to one of its stories called "Star Wars", and there the story would have begun
"The Journal of the Whills" has almost no, or little validity in the canon realm of Star Wars as we now know it.
It was originally, (as said by Padmé), the names of some Drafts of the Original Scripts, and at the beginning of the ANH Novelization, there is a blurb about Palpatine and the corruption of the Old Republic.
At the end, it says something to the effect of:
"From the First Saga,
Journal of the Whills"
