in my paragraph i mention a name of an author on my work cited page. and i talk about his ideas and thoughts etc.

Question

so how do i cite that. just (page number) or do i ever put a citation there.

Answer 1

There are different ways to refer to citations and it is helpful to consult a manual of style. The intent is for the reader to check your references. "...Smith states on page 57 of his book that...." would be one way.

Answer 2

Anonymous is right, and you are right, too. If you put the name of the author in your sentence, then all you need in the citation at the end is the page number. If the work is from the Internet, there are no page numbers, so simply listing the author's name is enough.
