The Lent Copy · the lead
A library's digital copy can be duplicated at no cost, and yet there is a waiting list. The queue is not a technical fact; it is a licence written to imitate a shelf.

Each entry takes one thing a physical book did without being asked, and asks what replaced it.
Lending something you cannot hand over.
Marks, and where they now live.
What a wall of books was doing.
Scroll, codex, paperback, screen.

A shelf shows what you have read, in what order, and how far you got. Nothing has replaced it.
The Shelf
Annotation used to be a physical act on a specific copy, which is why other people's marks survive to be read.
Marginalia
The single biggest change in the history of reading: a form you can open at any point and hold in one hand.
Portable Text
Buying a book and licensing a file are different transactions with different afterlives.
The Lent CopyCylibris is supported by presses, binderies and studios. No copy, no ranking — the mark and the name.
