Article citations generally have an author's name, an article title (in quotation marks), a journal title (in italics), volume and issue numbers, a year of publication, and page numbers.
Use the Journals List to see if we have access to the Journal (the name in italics) you need, and that we have access to the year you need. (You may also want to search the Wiley Online Library, since we have access to that collection through a different system.)
Book citations generally have an author's name, a book title (in italics), and a place and year of publication. Citations to chapters in books will include all of these things with the addition of a chapter title (before the book title, and in quotations marks) and an editor's name (after the book title).
