If it's all from one source you can put it at the end of the first sentence or at the end of the header.

So if it's a paragraph on cheese you can write:

Gouda (1)
wirjoaijfranjfkweitowqijaknflkajr

Cheddar
wihroianfjoianrfe


When in doubt, you could put it at the end of each sentence, and put the source in the first end note and just write "ibid" after every endnote.

But this is for MLA, i think..which now that I've scrolled back up..doesn't help you
