A sourced article is any work which has a verifiable source.
Star Trek Expanded Universe is an encyclopedia of existing and/or verifiable (once existed) Star Trek-based fan productions. In that vein, STEU does not allow "wiki-generated" stories or characters (created from scratch on this database). Not all entries must be sourced in order to be included on STEU, but it should be noted that any entry found without a verifiable source may be tagged with the {{unsourced}} tag, and may become subject to deletion.
Examples of verifiable sources
- Internet websites.
- Articles in any print-form publication.
- Transmission via radio, television or cinema.
See Category:Sourced and Category:Sources for listings of STEU source material.
