A list of pages that have been removed from the index but are kept. Their contents are preserved as they were at the time; newer content is on the pages that succeed them.
| Page | What it is | Why it is kept | Successor |
|---|---|---|---|
| A map of the walls | A map, as of September 2026, of what could not be reached in each problem | As a cross-section of what was closed and what was open at that time | The ledger of claims — Questions that remain |
| Taking stock of novelty | A list sorting what had been reached as of September 2026 under four labels | As a record of the sorting at that time and of the range searched. Theorem names are as they were then | The ledger of claims |
| What remains | Where the open items at the end of each article stood, as of September 2026 | As a cross-section of how the open items closed and how they changed shape | The ledger of claims — Questions that remain |
| An approach through residues (the Riemann hypothesis) | A withdrawn line of argument | To keep a withdrawn claim in a form that shows it was withdrawn | None (it stays withdrawn) |
| Drawing unsolved problems at random — the section "About this method" | The record of how the first round was conducted | As a section of the article. The thinking has been gathered onto a separate page | How the work is done |
| How far the published logs alone reach — the section on the nine discrepancies in the manuscript | A record of reading outside material | As a record of where things could not be read when reproducing from the public logs alone | None (kept within the article) |
