Book Builder (Puzzle)

Run ZIPs in → print-ready interior out. Each ZIP becomes a section; puzzles renumber continuously; the solutions section in back is rendered from the same data objects as the puzzles, so they cannot drift. Print to PDF at 100% scale for KDP.

Sections (in book order)

No sections yet. Load a run ZIP from the generator cache or import one.
Optional. With litariva-fonts.json loaded, the title, contents, dividers and how-to page can take a warmer face. The grids and word banks always stay on the clear one — a puzzle depends on telling I from l from 1.
Optional. With litariva-state-shapes.json loaded, a sub-theme divider prints its state's outline above the name, and the title page prints a map of the country with this book's states picked out.

Book settings

A puzzle drawn from a pool with no shared subject arrives with no heading, so in a mixed book some pages would carry one and some would not. This fills those pages only; a puzzle that already has a heading keeps it. It is a label you are choosing, not one read off the words — so it should be true of the section, like "Miscellaneous".
Should match the cover and the KDP Author field. The imprint stays on the copyright page.
Off draws a rule between grid and bank instead. A run generated after this setting existed carries its own answer and that one wins — this is the default for older runs. Solution grids keep their border either way: they carry no bank, so there is nothing for a rule to divide.
Printed above the title, smaller, as a series line. This is the page only — KDP’s own series fields are set in the listing and are what actually link the books together on the store.
Print-on-demand has no fixed print run, so leave this empty for a first release. Use it only for a genuine revision, e.g. “Second edition, revised and expanded”.
Printed under the rights notice, wrapped to the column at the book's text size. Empty is the default and is correct for a vocabulary book — a source note describes where the CONTENT came from, so Census wording in a Hodgepodge volume is simply false. It used to be the default here and rode into every book that did not clear it. For a Town by Town volume, paste:
Town and city names in this book are drawn from United States Census Bureau data: the Population Estimates Program Subcounty Resident Population Estimates (SUB-EST2025) and the American Community Survey 5-Year Estimates, 2024, table B01003. State outlines are drawn from the Census Bureau's 2023 Cartographic Boundary Files (cb_2023_us_state_20m). These are public domain works of the United States government. The Census Bureau has not reviewed or endorsed this book.
Falls on the first right-hand page after the copyright. The direction arrows are read off the finished puzzles, not drawn from a template — a book generated without reversals shows four arrows, not eight. A diagram that promises directions the grids do not contain is the kind of thing a reader notices on puzzle three.
A “Which print size?” block at the foot of the copyright page: the address in bold and, if ticked, a 1.5in code beside it. The copyright page is inside every Look Inside and has room at every type size — the rights notice is the one text allowed to step down, so it gives way to the block; the How to Play page cannot hold a code above 20pt without covering the arrows. Scan a printed proof before a book ships with a code.
One paragraph. Blank uses the default.
Prints the address itself at the foot of the How to Play page. The printed address matters more than a code for this readership — many will not scan one. A QR in a book is permanent, so point it at a path you control and can redirect, never straight at a form provider.
The encoder's format word was written mirrored until 2026-09-14 — the reason no phone would read it (§83). Fixed; its output now decodes under a reader validated against four commercially generated codes (qrfixture-check.js). Still off by default: scan a printed proof with a phone before a book ships with it. Max 42 characters.
Shown run together to explain the rule. Defaults to APPLE PIE. This is the only word in the book printed with no subject heading over it, so it is not taken from the puzzle list — a word that reads clean under On the Water can read very differently alone on the front page. The line is omitted entirely if the book holds no multi-word entries.
Add at least one section to build.
