Free Curricula CenterThe Free Curricula Center (FCC) helps students worldwide reach their educational potential by producing and distributing university-level curricula that can be copied freely and modified cooperatively. Specifically, FCC serves as a focal point for the development and sharing of textbooks, instructor guides, and other educational materials. These materials, called free curricula, are released at no cost into the public domain or under an "open source" style license. This license allows anyone to make and distribute copies without having to pay, and to modify the curricula as long as those modifications are released under the same terms. The Center helps its participants work together to create textbooks, instructor guides, and other materials for the subjects in which they have expertise. They do this by providing online tools to help educators collaborate successfully and by proving a space on the Internet where students can have free, easy access to their finished products. We also serve as a link to the resources of others, and mirror their material when permitted.
