Obtain permission to use anyone else's copyrighted material you are using in the workbook. For example, worksheets, explanations of material or word problems authored by someone else will require their permission for use. This is true even if the copyrights are not registered with the U.S. Copyright Office. Contact the person who owns the rights to the material and ask for his written permission to use it prior to publishing your workbook. When you register copyrights to the workbook, the copyright will cover only your original portions; portions created by others will still be owned by them.
