When uploading images or other media for use in Wikipedia articles, always remember to add the appropriate copyright tag to show what license the material is under, or if it is in the public domain. You can do this with the drop-down menu that lists common licenses, or leave the list on the default setting and add the template manually in the box above it.
While using a public domain work as the basis for a Wikipedia article may be a good idea (see public domain resources for a selection), please do not include large source documents within articles. We try to collect free (public domain or copyleft) source documents in a single place, Wikisource, where they can be annotated and translated. This reduces duplication across wikis, and frees articles from the context of the source documents. Keep in mind that Wikipedia articles are subject to merciless editing, so if a document is the subject of an article, yet is included in it, it might not be the same document for long! Even long quotation sections should be moved—to Wikiquote.
