How a signature is a folded section
One printed sheet, folded, becomes a nested gathering whose outer fold is the spine.
When the purchase is complete, return to the original window. It will refresh.
From the opening
A signature is one printed sheet folded into a section of the book so the pages fall in reading order. The outer fold becomes part of the spine, and the closed edges are opened when the book is trimmed or when a reader cuts them. The opening covers one sheet folded into pages, folio, quarto, and octavo, and the outer fold becomes the spine.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
