Using Third-Party Materials
When your article is accepted for publication, you must clear any required reproduction rights for any figures, photos, or text belonging to a third party, including any content found online, unless you can provide proof that no permission is indeed. Authors should request non-exclusive worldwide rights in all formats and media (print and online). Your journal's editor will require written correspondence attesting to the granting of permission.
Should a fee be required, please first check that the quality of the materials you would receive is acceptable to the journal. Please also note that contributors are responsible for clearing any fees related to the reproduction of any copyrighted materials.
Further information, including the preparation and technical requirements of these materials, can be found in the artwork section of individual journals' style guides.
If you're uncertain about the permissions necessary for third-party materials, below are resources that can offer advice on how to determine what permissions are required and how to understand when materials fall under the Fair Use Act or public domain. Please also feel free to contact your production editor.
