Q. How do I cite a direct quote when my source doesn't have page numbers?
Some texts, including older versions of Kindle ebooks, web pages, and Internet-only journals, do not have page numbers. When you quote from one of these sources, your in-text will be the same as a regular document would be with one exception: because these formats don't contain page numbers, provide a section heading and paragraph number (use para. before the number) inside the parentheses instead. This is also the way to cite html versions of articles.
