I searched for a cite on UDL using the OmniFile. I then took a screen shot of an article entitled, "Would You Recognize Universal Design if You Saw It?" and used the MLA format.
For the second cite, I used BibMe and looked up the book, "Follow the Drinking Gourd", and used APA format.
Both ways were easy to use, once I figured it out, but BibMe was very user friendly. My book had all of the information right there for you, but I did like the feature of being able to fill in whatever else you needed.
