Single Status Update
This is a Google Doc spreadsheet that cross-references written reviews for nearly 2500 WADs. Many of the older sites are only available via archive.org. It's a work in progress but it's come a long way since I started a month or so ago. I've tried to include a link to Doomworld Files pages for every item but the Doom diaspora did funny things like host stuff on Doom WAD Station or other, more temporal sites. The sources are listed by the time of the last written review with the newest being first.
