Often, a teacher will limit how many online sources you can use. If you find most of the information you need in the library, you can then use your online sources for details that you couldn’t find anywhere else. Since anyone can write something and put it online, it can be hard sometimes to sift through all of the material on the internet to find authoritative sources. To ensure you’re getting high-level sources, start by using an academic search engine, like Google Scholar, Lexis Nexis, or...
