 This is part two of the Citing Sources Tutorial, which will show you how to add citations on Wikipedia using the Site function in the Edit toolbar. From an Edit window, click the Site button, which brings down a bar of extra options. Here, you can click the Templates pull-down menu and then select which kind of source you're trying to cite, a generic web page, a news article, a book, or a journal. For this example, we'll go with a book. We're citing the part of this sandbox page that says being bold is important on Wikipedia, and I have a book that backs that up. So clicking Site Book brings up fields where you can put in the author, John Broughton, and the title, Wikipedia, the missing manual, and the year and publisher, and so on. Another way to go is to start with the ISBN. Then, you can press the Search button next to it, and it will fill in the rest of the info automatically. Another handy feature is the Ref Name field. Put in a short word or phrase to identify the source, I'll call this one Broughton, and it will be easy to cite the source multiple times without having to re-enter any info. If there's more you need to add to the citation, you can press the Show Extra Fields button, which lets you add co-authors, editor, and other details. Once you've added all the info you want for the citation, press Insert, and the wiki code for the citation will be added right where the cursor was when you started the citation tool. Add an edit summary, save the page, and you see the new citation, with a numbered superscript linking to the footnote, just like with a manually added citation. If you used the Ref Name feature, then when you make another edit to the page, you can click Named References in the Site Toolbar to pull up a list of all the named references in the article. Pick the one you want, press Insert, and it will add the code for another reference to the same footnote. Another feature of the Site Tool is Error Check. Press the button to pull up the error checking options. Select the ones you want, and press Check, and you'll get a Citation Error Report, listing any broken or duplicate references. And that's it! Happy editing!
