Not just written work is copyrighted--sound files can be copyrighted too even if they've never been written down. When you post a message to a message board, or even send an email, the copyright for that work belongs to the author in most cases. copyright.gov says: Copyright protection subsists from the time the work is created in fixed form. The copyright in the work of authorship immediately becomes the property of the author who created the work. Only the author or those deriving their rights through the author can rightfully claim copyright. Copyright protection is available for all unpublished works, regardless of the nationality or domicile of the author. The way in which copyright protection is secured is frequently misunderstood. No publication or registration or other action in the Copyright Office is required to secure copyright. The use of a copyright notice is no longer required under U.S. law, although it is often beneficial. Because prior law did contain such a requirement, however, the use of notice is still relevant to the copyright status of older works. So, for example, the email Mayrie sent this week describing a good process for validating books, is technically copyright by her and we cannot reproduce it without her permission. Now she can give blanket permission for us to pass along her written work to other volunteers and she can put stipulations on it like we can pass it along as long as we give her credit, or we can reproduce her work as long as we don't charge people for it, etc. Jamie in Michigan Currently Reading - Gone, But Not Forgotten by Philip Margolin I'm an eBay affiliate, click here before you bid!
