WikiJam:General disclaimer

From WikiJam

All works are copyrighted unless either they fall into the public domain or their copyright is explicitly disclaimed. If you use part of a copyrighted work under "fair use", or if you obtain special permission to use a copyrighted work from the copyright holder under the terms of our license, you must make a note of that fact (along with names and dates). It is our goal to be able to freely redistribute as much of the Pearl Jam Wiki material as possible, so original images and sound files licensed under the GFDL or in the public domain are greatly preferred to copyrighted media files used under fair use. You can request permission for a form letter asking a copyright holder to grant us a license to use their work under terms of the GFDL.

Never use materials that infringe the copyrights of others. This could create legal liabilities and seriously hurt the project. If in doubt, write it yourself.

Note that copyright law governs the creative expression of ideas, not the ideas or information themselves. Therefore, it is legal to read an encyclopedia article or other work, reformulate the concepts in your own words, and submit it to Wiki. However, it would still be unethical (but not illegal) to do so without citing the original as a reference. See plagiarism and fair use for discussions of how much reformulation is necessary in a general context.
