Readers interested in free online courses from universities around the world, such as those offered on platforms like Coursera and edX, may find Class Central to be a helpful resource. Class Central is a search portal and reviews site specializing in Massive Open Online Courses (MOOCs). It describes itself as "a giant curated catalog of MOOCs spread across different online course providers," specifying that "We focus on quality, and we manually categorize and tag every MOOC." Visitors can search for courses by keyword or browse by subject, university, or provider, and Class Central also points out notable and popular courses. Each course listing provides a descriptive overview, links to commonly asked questions about the course provider, a list of related courses, and reviews written by people who have taken the course. Users can choose to register for a free Class Central account to keep track of courses they're interested in. While not every course cataloged by Class Central is free, many (if not most) of them are, and those that are not are clearly marked. Launched in 2011, Class Central also publishes the MOOC Report, which covers news, trends, analysis, annual roundups, and other articles about MOOCs and online education.
