PubMed can quickly and efficiently help you to find an article when you only have a partial reference. You can find references where you have limited information e.g. only the author's name and the date of publication.
Simply enter your citation elements into the PubMed search box and the improved PubMed citation sensor will find your article in most cases. If you're having trouble with finding your reference using this method then consider using PubMed's Single Citation Matcher.
