Let’s take a look at some of the different types of sources you might use for your academic work, and consider the purpose, creation process, and product format of each.
Of course, these are not the only types of sources you will encounter. You may want to consult a scientific encyclopedia for an overview of a new-to-you process, or review government sites for access to regulations that might apply. Trade journals can be useful for insight into the industry, and pricing data can come from a variety of commercial providers. Check your Subject Guide for a curated list of links for your discipline.
