No copies of primary sources
While using a public domain work as the basis for a Wikipedia article often is a good idea (see Public domain resources for a selection), please do not include large source documents in 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 source documents from the context of a single article. Wikipedia articles generally should only include content that is open to merciless editing, with the exception of a few relevant quotes. Even long quotation sections should better be moved to Wikiquote.
