MEpedia:Copyright policy

Understanding copyright on MEpedia:

Contributions from editors

 * All MEpedia content is covered by CC BY-SA 3.0 License and GFDL license: in brief, this means that when you click save on an edit, you agree to release your contribution for revision and redistribution by anyone who wishes. This facilitates the circulation of knowledge on ME as well as collaboration among MEpedia editors. However, if you do not wish to grant this release of something you have created (whether text, photograph, or other medium), you should not add it to MEpedia.

Images and files from elsewhere

 * Licensing MEpedia under CC BY-SA 3.0 also means that all work submitted must be compatible with that license unless otherwise stated - do not add an image with a different copyright to a page without adding a caption for license information. You may only add work you created yourself and thus have legal right to grant the license for; or, work copied from a source with a public domain license or otherwise compatibly licensed for reuse. Do not add copyrighted work to MEpedia without first securing the correct license, for example a Creative Commons Attribution or Creative Commons Share-Alike license may be mentioned on a research paper, on a journal's website under the licensing and copyright orterms of use pages, or on a WikiMedia Commons image. As a rule, assume all work is copyrighted until you can confirm otherwise, even if it is publicly available to view.

Using an alternative license
Image with Creative Commons Non-commercial 4.0 license, license chosen on upload: Grey and white matter image

Use of image on page states both the correct license, and the citation or doi number/link. Displayed on page:

Open access is not a public domain license
This is not a type of license. It just means anyone can read it without paying. Most open access research will also have a creative commons license, which may be a non-commercial, or no-derivatives license that you need to display with the image.

Free access, HHS access, PubMed Central and Public access
None of these are types of license. They simply mean the full article and any images can be viewed without charge. This may be a condition of a grant awarded to the authors. This does not mean they are licensed for reuse. Check for a "Creative commons" or license statement on the article, or on the PDF copy of the article. There may also be Copyright and licensing information on the original journal's website. Unless it clearly states which license it uses, do not upload it or parts of it to MEpedia. Most articles marked "free access", "HHS access" or "Public access" cannot be reused on a website.

Royalty free images and clipart
This does not mean public domain or freely available for reuse. Royalty free images involve paying a fee to the website, either once or yearly, to reuse the images or material. Check the information on the website for details. Clipart images may be protected by copyright, or may be available for reuse; check the website for details before using.

Fair usage
Images not licensed for reuse may be uploaded with a fair use license in certain circumstances only, e.g.:
 * An photo someone posted on Twitter, if you have asked for the photographer's permission, eg for Millions Missing images
 * An image or file with another license that allows reuse, describe the license in the upload box
 * Copyright is known to have expired

Images of children
