NB. The following tools are no longer maintained and may not work. I recommend that you install the Citation Expander gadget in your user preferences (listed under "Editing gadgets"); this can expand a reference from just a DOI, PMID number, and often a URL.
Quick links:
If you are researching a topic and haven't found all the references you need yet, you can use a Google Scholar interface to find an article. A link below each result creates code you can copy and paste directly into Wikipedia.
Alternatively, if you already have some of the citation's details to hand, it might be quicker to use the form interface, which allows you to add as much or as little data as you like, then completes the rest of the citation for you.
If your search ends in a year, the engine will assume that preceding words are authors, and you are searching for papers from that year. For example, searching for "Nash 1950" produces this result.
If you enter a DOI or PMID/PMC id, that article will automatically be produced.
