For millions of students worldwide, free, open courseware provides a window, if not a front-row seat, to top university classes. The formats are as varied as the people who tune in. Some consist mainly of lectures recorded on iTunes, while other courses seek to replicate a classroom experience by offering study groups, computer-graded tests, and weekly assignments. And while you might get a badge or certificate showing you mastered the material, you generally won't get direct interaction with the professor, who may have recorded the lectures a few years ago. Here is a look at five introductory economics classes: four through open courseware and one in a traditional classroom.

Open access can be more than making research available to read, but also allowing others to re-use that research. For example, allowing the content to be analysed using text mining1 or reused for commercial purposes. Research data is also increasingly made available openly.
