It's not hard to get on a computer and find material on any topic using Google. Finding articles in databases that meet your instructor's requirements takes more skill and evaluation, not to mention time.
Through the Cañada College Library, you have access to dozens of databases, each one containing hundreds of thousands of articles from journals, newspapers and magazines as well as videos. View the library's guide to databases on the library homepage.
Many papers you'll write in college require "peer-reviewed articles." The "peers" reviewing these articles are experts in the same field as the author; for instance, physics professors will review a physics professor's article.
Who are the peers in 'peer review'?
A professor or other expert submits their article to the editor of a journal in their field. For instance, a psychology professor might submit an article to the Journal of Abnormal Psychology. A physicist would submit a paper to Applied Physics journal. The editors of these academic journals then ask the authors' peers - other professors or experts in this field - to evaluate the submitted articles. Those experts then submit their comments and reviews back to the editor, who returns them to the author, who answers the criticisms and rewrites portions of the article to satisfy his "peer" reviewers.
This lengthy review process explains why peer-reviewed journals - also known as scholarly or academic journals - publish only two or four times a year.
Your instructors want to know you can find peer-reviewed articles. This means using limiters to narrow your search results in databases to find these articles.
Librarians can help you with this.
