Pages: Cite an article from a journal

I want to cite an article from a journal, e.g. AMS.So in the journal, there are several articles from different authors.Actually I thought that in my bibliography I have to print "pages 56-67", when these are the pages where you can find the article.But now I read several times, that I use "652 pages" to show, that the whole journal has this amount of pages.What is correct?
