Adding page numbers into the citation, for direct quotes or for easier access to the original text
If you need to add page numbers to a citation, click anywhere in the citation (the background of the citation should turn grey to show it is selected).
In Word 2007, select the EndNote tab from the "ribbon", then click on Edit Citation(s).
In Word 2003, from the Tools menu, Endnote, then select Edit Citation(s), or use the button on the EndNote toolbar.
For some major styles (e.g. APA 5th) you can simply add the page numbers in the Pages field and EndNote will do the rest..
However, for some styles where this is not set up properly, you will have to add everything into the Suffix field that you want to see added to the in-text citation.
After you click the OK button, you should see the page details added to the in-text citation.
