Yes. All my work you can find on arXiv.org. When you submit there, you have to choose the license under which the arXiv can distribute, and two of the options are Creative Commons licenses. We submit our articles to the arXiv first, and then to journals. This means that when the journals receive it, they know the content is already out, and they're not going to get an exclusive distribution deal in any case. There used to be a "preprint" system in which major labs would physically mail around recent articles. The WWW started at CERN and is an outgrowth of this idea.
Everyone should use the arXiv. There are sections for many scientific disciplines, but far from all of them (all it would take is a request to start a new one). In many other fields, the journals exercise draconian control over the scientists (Medicine, Computer Science) and that needs to stop. They work for us, not the other way around.
But, I'm talking about journal articles -- I haven't written any books, and don't really intend to. For scientific journals I agree copyright is a useless hindrance. It was a nice tool when distribution is expensive, but now that the marginal cost of distribution has gone to zero, it's better done with a central government grant, and open access. Now we're just missing a peer-review/referee system attached to the arXiv. When that happens, the journals will die for good.
