   ARCHIVAL — exhibition room. Loaded on a/archival.html.

   TIER 2. A finding aid and its card catalogue: uniform units on aged
   paper, typewriter monospace with ink spread, call numbers leading every
   card, ruled fields in the same positions, alphabetical navigation
   exposed. Dense on purpose — the density is the argument. No card is
   bigger, brighter or otherwise privileged; rank is position in the
   ordering, which is why this sheet contains no emphasis classes at all.
