Frequently Asked Question
If you want permission to use some of my materials as part of a teacher training workshop, here is the answer.
If the material is from a book whose copyright is currently held by a commercial publisher, I believe the rule of thumb about fair use is that you can duplicate up to ten percent of the pages. This applies to Zome Geometry.
- If I hold the copyright (as is the case for almost all of the material on this site,) you have permission to use as much of it as you want, under these conditions:
- - You do not sell the materials,
- - You credit me as the author, and direct participants to this Web site
- - You let the participants know that they are bound by the same conditions
- Have a great workshop!
