The letters
Leave your name at the window
One list, one purpose: word when Entrustment is out, and the occasional note between now and then. Nothing else, and not often.
Your address is kept for that and nothing further. Leave the list at any time.
The founding window
There is a second ledger, kept shorter. Founding subscribers are entered for the advance edition — the book itself, before publication day — and for the technical record: how the artifact documents are made, and the material that does not run in the letters.
