Where you look depends on the kinds of information you need. This chart helps to illustrate how information is created and produced.
It can help determine where you'll go for the information you need. Good search strategies often include multiple types of sources.
Information to the left of the dotted line:
The information to the left of the dotted line is information found on the Internet, which includes Wikipedia, online news sources and broadcast media. This information is produced quickly; sometimes daily, hourly, or second to second.
Information to the right of the dotted line:
The information to the right of the dotted line includes information in electronic formats (found online) or in print formats. These types of information include books, scholarly journals, encyclopedia articles, and raw data. These information types can take up to months or years to produce. They cannot always be found on the free web (like in a Google search), but can be found through the library.
