Where to look for information depends on what type of source best suits your need.
See below for links to these sources. If this feels like too much to choose from, or if you have any questions, Ask a Librarian!
What we love about Google Scholar: Who DOESN'T love Google: powerful, fast, and bountiful!
What drives us crazy about Google Scholar: Many of the articles in Google Scholar are not full-text unless you pay money. Hint: We have found that citations with a "PDF" on the right side of the screen usually are full-text.
Not able to find the full-text for free? Send the citation (the basic information) to one of the librarians, and we will try to track down the article. Never pay for an article! If we can't get it for free, we might be able to pay for it, but you should never pay for an article!
What about Wikipedia? While sometimes controversial, Wikipedia entries can be great places to start - so long as you don't stop there. More information about how to use this source responsibly is under the tab for Wikipedia!?! .
