Folium X
A library in which an idea can find its sources—and its next question.
In development · not release-ready
The Higher-Order Library. A recursive epistemic system for books, evidence, interpretation and inquiry.
From a shelf to a question.
The product direction is for readers who want to follow relationships between books and ideas while keeping track of the material behind an interpretation. A useful encounter should leave the reader better able to examine a connection and decide whether it belongs in their own work.
