Explore Resources in the Creative Commons or Public Domain that Can be Used for Instructional Purposes

First of all, understand that you are able to link to any resources or tools on the web for instructional purposes. You are not able to copy ALL materials and add them to your own instructional works. It is best to stick to the Creative Commons and public domain. Alternatively, you should ask for permission from the author of the work.

Therefore, you will likely want to incorporate materials into your webpages, webquests, or multimedia that are from the Creative Commons or the public domain. In terms of the Creative Commons, it is recommended that you use materials that fall under the "Attribution" license. This is the least restrictive license allowing you to distribute, re-mix, and alter the materials. The only thing that you must do is cite the source and give attribution to the author or creator of the work. Make sure that you always check that the license is indeed an "Attribution" license.

Here are few places that you can explore to find materials in the Creative Commons:
 * Creative Commons site (all kinds of materials)
 * Flickr (images)
 * Wikimedia (all kinds of materials)
 * Google Advanced Search (Under "usage rights", choose the least restrictive license)
