Each course we publish requires an average of 100 hours of effort to produce, and OCW typically publishes materials from 60 courses on our site each year. In addition to MIT faculty, behind OCW is a dedicated team of about 20 publication specialists, intellectual property managers, web and technical production managers, video editors, and administrators who work directly with faculty to collect and compile course materials, ensure proper licensing for open sharing, format materials for our site, and manage OCW’s communications, outreach, and operations. OCW sustains a considerable technical infrastructure to manage content and distribute it through a worldwide network to our global audience. Supporting rich media, such as our very popular video content, can be especially costly.
