If something is untitled do you . . .?

Question

do you leave the title out or call it untitled in a bibliography?

Answer 1

I looked at the MLA style manual, and it doesn't specifically say what to do about untitled works. However, there are several points where it notes that you should include as much information as possible. I would note that it's untitled, so it's clear that you're not leaivng the title out, or say "No known title".

Answer 2

Untitled simply is a default title applied by a program which needs to be replaced by the operator.
