Links for Wikipedia Page and Citation Concerns

I thought up a cpl of link words for my racetrack. I figure "horse" "harness racing" "Hazel Park" "racetrack" is a good start to introduce the basics of my topic. One thing I'm worrying about is how we would go about citing a source that isnt electronic; say a newsletter or a pamphlet. Hopefully we go over this in class soon.

Link to Hazel Park Raceway

Heres a link to Hazel Park Raceway, my Wikipedia topic. It should be interesting, for as long as it's been around, I've never once set foot in there.
