Free? to good home

I've just been given some old typewriter supplies - IBM Selectric ribbons/cartridges, etc - still in their packaging, and rather than just throwing them away, I'd like to get them into the hands of those who can make good use of them. What are my best options? Craigslist, freecycle... anyone else?

EDIT: Delivered to UO Geog, thank you pjack.
