I often grant permission to use my content for a special purpose. These guidelines are my inclinations based on my experience and reading, just so you know where I am coming from.
Attribution - Attribution means identifying the sources of content in your publication that you did not personally create. I take care to identify sources in all my publications, and I expect and require that anyone publishing or using my web content does the same.
Photography - To use a photo of mine in your book, flyer or school report, I require:
Text - To use of any of my text in your book, flyer or school report, I require:
Duplication of Web Content - What I most like about the worldwide web is its broad diversity of freely and quickly accessible original works. The more independent content choices available, the better we the public are served. Surfing the web can be an inspiration and a great learning experience. On the other hand, duplicated web content adds nothing new to the experience, and it slows discovery of additional perspectives, information or art. Duplication also tends to diminish the rank search engines assign to the original posting web site. So even as duplication interferes with finding new content, it is the original content creators who suffer most, both financially and in terms of morale. For these reasons, I prefer that my content normally be on my web site only, and I prefer that other people's content be respected as uniquely theirs. But please do contact me if you have a special request. I have been persuaded to share content in the past, especially when it was for a charitable purpose or for a short-term need.
Links - Good web authors don't copy without permission, but they do link. The network of links among sites is what powers the worldwide web. I link to other people's pages when I feel that their pages will add value to the theme of my page. If you feel that visitors to one of your pages would benefit from a page of mine, please do link. No special permission is required. However, never link in a way that omits or hides the attribution or the URL from end users.
