IWTL what the heck an ABRIDGED bibliography is!

My research paper is due tomorrow and this + citations is all I have left to do. My professor specifically told us to write an abridged bibliography, which I can find absolutely nothing about online--only annotated bibliographies. Are these the same things under different names? If so, I'd also love a clear and concise template or example to help me learn how to write one. Thank you in advance.
