Types of information sources

Information can come from virtually anywhere — media, blogs, personal experiences, books, journal and magazine articles, expert opinions, encyclopedias, and web pages — and the type of information you need will change depending on the question you are trying to answer. Look at the following sources of information. Notice the similarities between them.

A magazine is a collection of articles and images about diverse topics of popular interest and current events. Usually these articles are written by journalists or scholars and are geared toward the average adult. Magazines may cover very "serious" material, but to find consistent scholarly information, you should use journals.
