Library Research Guide
K-State Libraries has resources that provide different types of information. Primary sources are created by and for experts in an area of study, so that might not be the best place to start learning a new topic. Encyclopedias or textbooks are less specific and cover broader topics so are easier to understand for audiences with less experience on a given topic. News articles have the broadest audience and are written by science communicators so that's a great place to start when learning a new topic.
Dissertations usually cover one thing in 4-6 years' worth of detail but have introductory sections that may make sense to a broad audience before diving deep in one aspect of a topic.
