This guide can help you with a few essential skills:

• Being able to tell the difference between primary literature and secondary literature (review articles, etc)
• Searching for known articles using Google Scholar, and then using the 'cited by' feature to to track the research conversation forward and backwards in time
• Using subject-specific library databases, from the Finding Articles tab, to search for primary literature related to your research topic

It also can help you start using the really useful (and free!) citation management tool called Zotero, which can help you easily save articles as you find them, and then easily create properly formatted bibliographies. For more information, check out the Installing & Using Zotero tab.
