Okay so I'm writing a problems/solutions paper in MLA format and I must cite the sources being used using parenthetical citations.

I have a few questions that maybe you smart asses can answer that I've been having trouble resolving on my own through my own searching.

1. When you paraphrase a source from a pdf document that has NO page number, how in the hell do you cite it? I read somewhere that for an HTML document you're supposed to cite it by only using the author's last name (but it didn't say you do the same thing for a pdf document). For example:

PDF document

Ted Johnson, of the Brookings institute, asserts that many kids who suffer from Diabetes type I are more susceptible to contracting liver disease later in life (Johnson).

Would that citation at the end be correct? Not the bullshit statement I made up about Johnson's assertion, but how the source was cited if its from a pdf document without a given page number.

Thanks for the help.
