College research and writing is an opportunity for you to explore high-level, academic resources written by experts in the field. You may not have ever seen these types of resources before. These documents come in many forms, including:
This is in additon to the types with which you may already be familiar: books, popular magazines, association/organization websites, videos on YouTube or Netflix, brochures/pamphlets, etc. etc. etc. These resources are all useful in academic research, as long as you are a good judge of accuracy and expertise of the author.
These types of information can be found through Google, in print, and through Academic Databases.
Reading these resources can be more challenging due to more academic language (big words! jargon!), length (long! with no pictures!), and content (assumes you already know some things about the topic! maybe seems a little dry). As you continue with your college career, these types of resources will become more important to you as you become an expert yourself.
