Adding citations to Wikipedia articles is certainly important, but also sometimes tedious. Unless you're using the Visual Editor (and you should be!) you have to remember all the specific code so you can add key details like publication name, date, and link.
There has to be a better way. And there is! Wikipedia offers a handful of citation tools to help semi-automate this task:
Cite4Wiki is an add-on for Firefox that opens up a contextual menu for adding key information
Wikicite is a Windows program that does basically the same thing
reFill is a tool that can turn URL-only references into fully formatted citations
Zotero is an independent service useful for managing references when doing research
The truth is most editors still write citations by hand, or expanding snippets, which they're used to. If you're just getting started, it might be worth experimenting. But we still recommend the Visual Editor.
