Frog God Games has announced that it is giving away Swords & Wizardry Complete.
Not a no-art version or even limited version, but the entire game free of charge.
You can go to their website and grab a free PDF (print still costs you).
or you can also get it here (from my downloads).
You can also get copies of their other rule sets based on it for free as well.
While not my go-to game, it is a lot of fun and great set of rules for old-school gaming.
Though I do have to admit that Erol Otis cover is rather cool.
If you have The Witch or Eldritch Witchery then you can download my S&W conversion guide to play a Swords & Wizardry Witch.
