Often, people wish to "donate" copyrighted materials to Wikipedia. These materials may be text (including monographs, articles, etc.) or images (including photographs). They may or may not already be posted on some other website. They may or may not actually be appropriate for inclusion in Wikipedia. This page exists to provide some guidance in these matters.

(Most of what is on this page also applies to work in the public domain, but the focus is on copyrighted materials, because they raise more complicated issues.)
