Agreement for Use of Web Materials

Thank you for your interest in my web site and learning tools.

You may use, download, and reproduce documents or images at this site for educational purposes, on the condition that you give credit to the author. If you modify one of my pages and print it or post it on the web, you must include the statement, "Copyright 2022 (or current year), Aaron Keller, adapted by permission." On the web, the name Aaron Keller should be a link back to the original page at my web site. If you want to use a page without modification, please simply link to the page at this web site.

All original materials at this web site are the property of Aaron Keller, and may not be included in any commercial publication without a licensing agreement.

Support This Site

Teachers: Please support my activities at this web site by requesting permission to include any of these materials in your courses. Simply send me a brief e-mail telling me how these materials fit into your plans, and how many students will be using the site or printed files. I will deeply appreciate a brief, informal e-mail report at the end of your course, including corrections, suggestions, and descriptions of how you modified my materials to suit your needs.

Why Ask For Permission?

Unlike peer-reviewed journals, the web at large has no quality control. The primary indication that a web document is useful is that people use it. By asking permission, by specifying how you will use materials, and by giving feedback later on, you give authors proof that their work is attracting readers and users. Unlike counts of web access to documents (so-called hits), requests for permission and feedback are meaningful forms of peer evaluation from the web audience. By reporting your results, you also support further improvements. If you believe that useful web materials constitute worthy scholarship, then let web authors use your permission requests and your feedback to help win support from colleagues for their efforts.

Asking permission and keeping my name on modified forms of my work also protects me. If someone were to include my work in a copyrighted publication and call it their own, I could lose the right to distribute my own work. In such an instance, I would have a stronger case for protecting myself if my name were connected to all apparitions of my work at my own web site and at others.

Thank you for your interest in my web site.
