Memory Alpha:Database download
From Memory Alpha, the free Star Trek reference.
The Memory Alpha server automatically generates dumps of the MediaWiki database every night. These XML dumps are available for download for backup purposes and for offline reading. You can click the link below to download the most recent backup of the database. Only the current version of each page is included in the download. As of March 2008, these downloads are approximately 118 megabytes in size.
Alternatively, you can go to the dumps directory and download the full database (~672 megabytes, compressed, as of July 2008).
