Question

Can you do a double MLA in text citation like this?
"some classical plays (Umberger)(52, 179,Cogan). "

Answer 1

It's better to put (Umberger and Cogan 52, 179).

Answer 2

even if they are 2 different sources?

Answer 3

If they're 2 different sources, you should cite them independent of each other. You would only cite 2 authors together if they wrote the same book. :)

Answer 4

Cite the original (oldest) source.
