Explanation of Copyright Notice

Federal copyright law protects everything we posted here related to our GreenTree series. (In fact, copyright law protects any original work that is preserved in some medium (electronic, book, tape recording, etc.), whether or not a copyright notice is attached. Copyright is assigned to the authors unless the authors assign it to their employer, publisher, or someone else.) Note that federal law protects the _presentation_ of the material. Thus, these handouts can not be reproduced or distributed, in whole or in part, printed or electronic, without our permission. Federal law, however, does _not_ protect the ideas and facts contained in this website. The ideas and facts can be freely used without obtaining copyright permission from us (just as we have freely used the ideas and facts from books and articles without obtaining copyright permission from others).

Scholarly practice is different from federal copyright law. Scholars acknowledge the sources of ideas and facts and do not present other's work as their own (this would be plagiarism). Throughout our handouts we have acknowledged the ideas and information that we gained from other sources, by giving names of individuals and book information. Many of the ideas are our own, and we are happy to share them with others. We simply ask that if you draw on our material in your own presentation that you acknowledge us as the source.

In short:
- If you want to distribute this material (i.e. photocopying the handouts for a group, emailing the text to a group, etc.), ask our permission first.
- If you want to recommend our web site to others, you do not need to ask permission (and we're glad for the extra publicity!).
- If you want to use our ideas in your own work (book, talk, article, etc.), acknowledge us as the source.

Thank you.
