Surely the need for strict control of the 1970s Packet Radio Notes has
passed by now.  Is there a full archive of them publicly accessible
somewhere?

Is there a list somewhere of all the issued Packet Radio Notes?
Which could perhaps be used to anchor searches for all of them?

ARDC.net and the Internet Archive are collecting a Digital Library of
Amateur Radio and Communications, which would probably be happy to host
this collection.  See:

A web search for "Packet Radio Note" turned up exactly one reference,
which is hidden inside ACM's "digital crypt" where papers check in and
never check out:

  Abstract: The application of packet-switching techniques to radio
  channels has provided a solution to many computer-communications
  problems previously unsolved. For example, a packet radio network can
  readily be designed to provide area coverage at data rates fast enough
  to support interactive operations for thousands of users having a
  variety of terminals such as hand-held devices, TTY-like devices,
  display devices, computers, and unattended sensors. Since the
  interconnections are by radio, the users can be fixed or mobile, and
  the network can be easily moved. Furthermore, it can be readily
  established in remote or primitive areas where a wired network would
  be impossible, and total connectivity of users will be provided.
