If your research assignment required "peer reviewed" or "academic journals," it's quite easy to ensure your sources meet that requirement.
Start with the databases available to you through Muskingum University:
On the left side of the Library's website, click on "Databases." You'll see this image, with the alphabet below it:
If you already know the name of the database you should use, click on the letter appropriate to the first letter of the database and scroll until you find the one you want.
If you don't know which database(s) to use, the "All Subjects" pull-down menu is very helpful. Using that pull-down menu, look for your academic subject field (English, Sociology, Physics etc.) and click on the academic subject. If you're looking for a specific type of resource, for example, newspapers, the use the second pull-down for your type of resource. The "Best Bets" from either search will be grouped at the top of the result. Please note that the databases are in alphabetical order, so the first database isn't always the BEST one. For a good search of resources, you should never limit yourself to just one database if multiple databases are suggested.
If you're doing general research or are taking an introductory course, consider using "Academic Search Complete" as your starting resource: it's a great general database.
