Ha, just saw this so perhaps some repeat from the previous post. Well for one there are no rules here, really. Trying to be respectful of each other, sharing knowledge, art, music etc. For example I can just say, hey check out this cool song:

But with text it seems that fiction can be spread over several posts.

Non-fiction or research this is perhaps a bit harder as if each post is meant to be a discrete post, then perhaps it is best to put all of the references in the reference list for each part (i.e. each post). That way any reader can pick up your post and see the references for that post. That is perhaps what I would do as there is more utility for reader. Good luck with your research!

Hope that helps and enjoy the song.
