I uploaded the 7,000+ Friedman NSA docs to the Internet Archive and
   used the metadata to rename the titles into something a little easier
   for humans to read and sort.

   The complete set of Friedman docs are also included in the NSA FOIA
   vault at [2]https://archive.org/details/NSA-FOIA-Vault
   ([3]https://archive.org/compress/NSA-FOIA-Vault to get the entire vault
   in a single zip). To grab just the Friedman docs and not the rest of
   the NSA FOIA vault, go
   to [4]https://archive.org/download/NSA-FOIA-Vault/Friedman%20Documents.
   7z   -- I should point out that the collected version includes the
   metadata file, but file names are unchanged and unassociated with human
   readable titles.
   These are the same copies released through the NSA's website, just a
   bit easier to sort and read.
   Enjoy.
