Tracing the History of the Computer - Copyright Notice
 

The license ComputerNostalgia.net uses grants free access to all article content and photos on this site in the same sense as free software is licensed freely. This principle is known as copyleft. That is to say, ComputerNostalgia.net articles and photos can be copied, modified, and redistributed so long as the new version grants the same freedoms to others and acknowledges the authors of the ComputerNostalgia.net article used (a direct link back to this site is satisfactory). ComputerNostalgia.net articles and photos therefore will remain free forever and can be used by anybody subject to certain restrictions, most of which serve to ensure that freedom.

To fulfill the above goals, history of computer articles and photos contained on ComputerNostalgia.net are licensed to the public under the GNU Free Documentation License.

Contributors' rights and obligations

If you contribute material to ComputerNostalgia.net, you thereby license it to the public under the GFDL (with no invariant sections, front-cover texts, or back-cover texts). In order to contribute, you therefore must be in a position to grant this license, which means that either

  • you own the copyright to the material, for instance because you produced it yourself, or
  • you acquired the material from a source that allows the licensing under GFDL, for instance because the material is in the public domain or is itself published under GFDL.

In the first case, you retain copyright to your materials. You can later republish and relicense them in any way you like. However, you can never retract the GFDL license for the versions you placed here: that material will remain under GFDL forever. In the second case, if you incorporate external GFDL materials, as a requirement of the GFDL, you need to acknowledge the authorship and provide a link back to the network location of the original copy. If the original copy required invariant sections, you have to incorporate those into the ComputerNostalgia.net article; it is however very desirable to replace GFDL texts with invariant sections by original content without invariant sections whenever possible.

      

Using copyrighted work from others

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 ComputerNostalgia.net's 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.

Never use materials that infringe the copyrights of others. This could create legal liabilities and seriously hurt the ComputerNostalgia.net 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 perfectly legal to read an encyclopedia article or other work, reformulate it in your own words, and submit it to ComputerNostalgia.net.

Linking to copyrighted works

Linking to copyrighted works is usually not a problem, as long as you have made a reasonable effort to determine that the page in question is not violating someone else's copyright. If it is, please do not link to the page. Whether such a link is contributory infringement is currently being debated in the courts, but in any case, linking to a site that illegally distributes someone else's work sheds a bad light on us.

If you find a copyright infringement

It is not the job of ComputerNostalgia.net to police content for possible copyright infringement, but if you suspect one, you should bring it to the attention of someone at ComputerNostalgia.net. Others can then examine the situation and take action if needed. The most helpful piece of information you can provide is a URL or other reference to what you believe may be the source of the text.

Some cases will be false alarms. For example, if the contributor was in fact the author of the text that is published elsewhere under different terms, that does not affect their right to post it here under the GFDL. Also, sometimes you will find text elsewhere on the Web that was copied from ComputerNostalgia.net. In both of these cases, it is a good idea to make a note in the talk page to discourage such false alarms in the future.

If some of the content of a page really is an infringement, then the infringing content should be removed, and a note to that effect should be made on the talk page, along with the original source. If the author's permission is obtained later, the text can be restored.

If you are the owner of ComputerNostalgia.net-hosted content being used without your permission, then you may request the page be immediately removed from the site.
