Date and place
Where were you when the idea turned up? A walking route, a half-read book, the edge of sleep. Context is how you find a thought again — record it before it flies.
A field guide to your own mind
Specimen no. 001 · 19 MarA thought, pressed flat the moment it landed. Recognizable on return — that is all a note needs to be.
Marginalia is a field notebook for the working mind — a place to record the specimen of an idea the moment it appears, pressed, dated, and classified for later study.
Open the notebookWhere were you when the idea turned up? A walking route, a half-read book, the edge of sleep. Context is how you find a thought again — record it before it flies.
Enough to recognize it later, nothing more. A sentence, a sketch, a quote — the notebook keeps the sighting, not the essay.
Return in a week, a season, a year. Old sightings become new ones when the rest of the notebook has grown around them.
The naturalist does not trust memory. She trusts the record.
