+Many of the changes which were first encountered outside of the Bell System in UNIX System V truly had their start in UNIX/TS 4.  Examples of such features which originated in UNIX/TS 4:
   * The Common Object File Format (COFF)
   * The LP Print System
   * Semaphores, Shared Memory, and Message Handling (IPC) matching System V introduced in 4.1
-  * The SGS (System Generation Software)
+  * The System Generation Software (SGS)
   * The termio terminal handling framework
+Current documentation proven to exist for UNIX/TS 4 include:
+  * Documents for UNIX Release 4.0 (https://www.tuhs.org/Archive/Documentation/Manuals/Unix_4.0/)
+  * UNIX Reference Guide Release 4.0 (https://www.tuhs.org/Archive/Documentation/Manuals/Unix_4.0/UNIX_Reference_Guide.pdf)
+  * UNIX User's Manual Release 4.1 (3B20) (Restoration/Archival in Progress)
+  * UNIX Programming Starter Package (https://archive.org/details/unix-programming-starter-package)
+  * UNIX Text Editing and Phototypesetting Starter Package (Archival in Progress)
+  * Note: the two above "Starter Package" documents are simply a subset of the Documents for UNIX set, so the content as of present is available in that collection.  There are later versions of these manuals which swap out Bell Labs icons and labeling with AT&T.  It is unknown at present whether these are simply cover facelifts or represent revisions to the papers as well.
+Additional documentation cited in the above:
+  * UNIX Administrator's Manual Release 4.1 (3B20)
+  * UNIX User's Guide
 Note: This is material that is, as of this typing, being actively uncovered and investigated, so this content will be in flux as time goes on.
