Looking to bring some Celtic background material into you Castles & Crusades (or other OSR games)? How about Roman, Greek, German, Nordic and Slavic? If so, the Mythos Collection is your bundle.
I literally have these books in hardcover sitting behind me, stacked in a neat little pile waiting to be read and integrated into my Swords & Wizardry Light campaign. At six bucks a PDF these are a bargain for endless inspiration.
