Unequal lengths, because a shelf is never full. The middle bar is short and vermilion — it is the item you came for. The whole identity is that one idea, repeated at every scale.
Never eyeballed, never evened out. The asymmetry is the mark — a tidy version of it reads as a hamburger menu.
So the mark holds at any weight of reproduction, from embossed leather to a 16px favicon.
In one-colour reproduction the middle bar becomes a knockout instead. It is never simply dropped.
Horizontal only. A vertical version was tested and reads as a barcode, which is the wrong institution entirely.
Five segments, read left to right, coarse to fine. It appears on spine labels, wall text, tickets, the website and the search field — always in mono, always vermilion at the level currently in focus.
The grammar was designed before the logo. It had to survive being handwritten by an archivist in 1974 and parsed by a search index in 2026 — so it uses no characters that a person could confuse, and no segment longer than four.
Horizontal for print and screen, stacked for banners, reversed for the dark estate, and vermilion for the exhibition programme only.
The archive is beige by nature, so the palette does not fight it. Vermilion is reserved for the active index level and for exhibition identity — nothing else in the building is allowed to be red.
Anything an archivist wrote down is mono. Anything the archive says in its own voice is the grotesque. Visitors read the difference without being told what it means.
One system, eleven touchpoints. The shelf mark is the connective tissue — it appears identically on the ticket in a visitor's hand and on the box they eventually open.
No fades in isolation, no scaling. Every transition is lateral or vertical, because that is how the building itself moves.
