Additional documents.

These documents may or may not be included in the volumes above, but it is felt that having direct access to them may be useful to some researchers. Certain important exhibits, such as "Rainbow 5" and the "Fourteen part message", will be included in this section so they can be accessed directly without searching through all the indexes and TOCs of the nine Reports. (The zip files for each Report will contain the entire text, even if it is redundant, to preserve the original contents.)

We have "broken out" the exhibits below into stand-alone PDF files. This will, we hope, make it much easier to find the documents in question for reference purposes.
