Periodicals
Periodicals include magazines and journals, as they are published periodically. There are many library databases that can access periodicals from around the world and from years past. A common database is Academic Search Premiere (a similar version is Academic Search Complete). Many databases, like this one, allow you to narrow your search terms, which can be very helpful as you try to find good sources that are relevant to your topic. You may start by typing a key word into the first box and searching. Sometimes a general search like this can yield thousands of results, which you obviously wouldn’t have time to look through. In this case you may limit your search to results that have your keyword in theabstract, which is the author-supplied summary of the source. If there are still too many results, you may limit your search to results that have your keyword in the title. At this point, you may have reduced those ten thousand results down to a handful, which is much more manageable.
Within your search results, you will need to distinguish between magazines and academic journals. In general, academic journals are considered more scholarly and credible than magazines because most of the content in them is peer reviewed. The peer-review process is the most rigorous form of review, which takes several months to years and ensures that the information that is published has been vetted and approved by numerous experts on the subject. Academic journals are usually affiliated with professional organizations rather than for-profit corporations, and neither authors nor editors are paid for their contributions. For example, the Quarterly Journal of Speech is one of the oldest journals in communication studies and is published by the National Communication Association.

If your instructor wants you to have sources from academic journals, you can often click a box to limit your search results to those that are “peer reviewed.” There are also subject-specific databases you can use to find periodicals. For example, Communication and Mass Media Complete is a database that includes articles from hundreds of journals related to communication studies. It may be acceptable for you to include magazine sources in your speech, but you should still consider the credibility of the source. Magazines like Scientific American and Time are generally more credible and reliable than sources like People or Entertainment Weekly.
