The Archive Internal Memo #2B0N2B
Type: Classification Guide
Subject: Archivist Personnel Categories

Archivists, be they field agents or support workers, are assigned code names and numbers upon joining the Archive. The numbers are immutable and may not be changed for any reason; code names are strictly discouraged from being changed but this may be permitted at the sole discretion of the Head Archivist. It is also strictly prohibited for Archivists to refer to themselves by their legal name (or former legal name); it is also forbidden to use legal or former legal names, if known, to refer to other Archivists. This is to preserve operational security, promote personal safety, encourage consistent nomenclature across systems, and prevent a recurrence of “The Two Johns” incident from 1967.

The following categories are authorized:
A – Living human beings or former human beings that can still pass for human.
B – Living extraterrestrial (“alien”) beings that can pass for human.
C – Non-corporeal beings, including spirits, souls, specters and the like, that are invisible to the unaided eye.
D – Demonic or infernal beings, angels or angelic beings, and other belief-based constructs that can pass for human.
E – Living human beings or former human beings that cannot pass for human or are otherwise unsuited to field work.
F – Living extraterrestrial (“alien”) beings that cannot pass for human.
G – Noncorporeal beings, including spirits, souls, specters and the like, that are visible to the unaided eye.
H – Constructs (computer systems, robots, automata) possessing self-awareness, regardless of form.
I – Miscellaneous beings not fitting into any category above
J – RETIRED and UNAVAILABLE for assignment (see AC-1985-OC-2 through AC-1985-OC-227).
K – RESERVED for future use (see Head Archivist).
L – Sentient or sapient plants, animals, fungi, lithospheres, biospheres, or similar.
M–X – Currently unassigned, to be populated by reassignment from Category I as needed.
Y – The Everlith.
Z – Horror vacui.

Note From Head Archivist:
I am not entertaining questions about category J or category K at this time. Requests for comedy reassessment to category K are not as funny as they seem, and may insult Archivist L426 “Sporovich.” Trust me, you do not want to be on its bad side.
