Moodle

Information literacy is by far one of the most important elements of public librarianship and can take many forms such as teaching basic computing skills (how to use Word for instance), helping senior citizens navigate the Medicare Program website, or creating research guides for using the library.

Moodle is a "course management system designed to help educators who want to create quality online courses. The software is used all over the world by universities, schools, companies and independent teachers. Moodle is open source and completely free to use."

Perfect for the public library, no? Sadly a look through their directory comes up empty for public libraries in the US. BUT I found a pretty good example (login as a guest) put out by the 21st Century Fluency Project, which taught a course on moodle "Powersearching in a Web 2.0 World" which is essentially a perfect information literacy topic for a library to cover.
