You have permission to copy PDFs purchased from Well-Trained Mind Press for use in your immediate family. This does not infringe copyright. However, if you take the PDF to a copy center, the center may decline to make the copies. The corporation may not wish to risk infringement lawsuits, and the employee may not wish to risk being fired. If this is the case, show the staff member the copyright page, which includes the copyright policy.
If you need more assistance, ask the Copy Center to call us and we can establish permission over the phone, or they can fax their permission form to us and we will do what we can to provide documentation and permission from our end.
