Okay, so once you know what kinds of sources you need to meet your information needs, where should you look for them?

Once more, thinking about categories can help. Where sources are located is generally organized by audience expertise level—by whether they are popular, professional, or scholarly sources. Popular and professional are often grouped together. But scholarly sources tend to hang out by themselves. (That’s why searching Google Scholar locates more of them than just plain old Google, and an academic library has more scholarly sources than a public library.)

Before you start looking, try the Plan for Sources table below along with the suggestions made in this section to think through what sources you’ll need for your own research project. Having your Plan for Sources always at your side while you search for sources will guide where you look and what you’re willing to accept. It will help you keep track of whether you have found the right resources.
