CopyTalk Webinars from ALA – http://www.ala.org/advocacy/pp/pub/copytalk
The American Library Association’s OITP Copyright Education Subcommittee sponsors webinars about copyright and fair use. While the main audience is for librarians, they are free and open to the public. They come out the first Thursday of each month.
Their webinars are also advertised on their “District Dispatch” blog, which has a category devoted to copyright issues.
