Here you can digest how to use Wikipedia in bite-sized morsels. The tips listed below were created for the Tip of the day project, or the Styletips project, but are listed here by title and organized by subject area for your convenience.
Sometimes it is preferable to refer to a section of a page when linking, rather than to the whole page. You can create a link to any subheading on any page in Wikipedia by including a # followed by the subheading at the end of a link.
Bookmarklets are Javascript programs that are stored as bookmarks in your browser, and which run when you click on them as opposed to bringing you to a page like a normal bookmark. Here is one that conducts a search in Wikipedia on any text you happen to have highlighted in whichever window you are in (or if no text is highlighted, presents you with a popup search box): ~axel/bookmarklet.html. See also Bookmarklets.
