The ordered register of works — each entry a thing known, placed, and findable.

A part that keeps its own shape inside a larger whole. A component can be taken out and still be itself.

Bodies of collected text taken together as material to study. A corpus is defined by what was gathered, and its edges are a decision.

A body of collected text taken as material to study. Its edges are a decision someone made.

The account of where a word came from and how its meaning moved. Etymology explains a word's history; it does not settle its present use.

A kept collection meant to be drawn on by others. Its purpose is not storage but retrieval.

Reasoned; of a register, one where every entry carries its scholarship.

A pointer from one thing to another. A reference holds no content of its own — it holds a way to reach content.

The waiting place that keeps things findable — where a thing rests, visibly, until its moment.

A column set beside the main matter. Placed alongside rather than within, so it can be passed over without loss.

A kind, recognised by the marks its members share. From the impression a blow leaves behind - the shape struck once and repeated after.
