Bottle them.

Peel, core, and slice, and cook down with some sugar until they start to break up, and bottle. It is essentially ready made apple pie filling, also very nice on cereal. I'm sure you can think of more.

Alternatively, if you have a cool garage or such like, just store them. Make sure any you're storing are clean, dry, and undameged, and loosely pack them in newspaper, in a box. so long as som air can get in, and it stays dark, they should keep until spring.
