Copyright Explanations

In general, please treat the permissions here as the beginning of a conversation, not the end. If you reuse one of my works, I’d love to hear about it, especially if you do something transformative and clever with it. And if you’d like to do something that would require further permisssion, please contact me also. The necessary rights aren’t always mine to grant, but where they are, I’ll give serious consideration to any polite request.

Note also that you have a number of blanket privileges under copyright law that apply regardless of whether I’ve specifically granted permission or not. First, copyright doesn’t protect ideas, only particular expressions of them. I’ll be upset if you plagiarize my ideas, but that doesn’t give me a legal right to stop you. Second, United States copyright law contains numerous specific exceptions, although the conditions are often quite technical. Third, you have extensive fair use rights. In general, the following kinds of uses tend to be legal (but remember that this list is not exhaustive):

Except where I’ve provided more specific requests, when I license a work under a Creative Commons license, I require that the attribution notices you must provide under those licenses indicate:
