Books are OG protocols
A two-thousand-year agreement between hands, eyes, and the trades that make books. Then: what happens when the factory fits on a laptop.
Jenna Dixon, [jdbb] studio
You are reading this on a scroll. Sequential access only, no flipping ahead. Hold that thought.
The seesaw never stopped.
A codex, digitized, comes back as a scroll of pages. Glaister's Encyclopedia of the Book on archive.org — a workshop participant pointed us to it this week — the most random-access kind of book there is, served in sequence.
Every book that goes online decides again: pages or scroll? Reflowable EPUB is a scroll; the print PDF is a codex. The factory makes both. The author chooses.
This talk, in the same view.
Thirty screens, laid out the way archive.org lays out a book. You will see them one at a time, in order — a scroll. Here they are all at once — pages. Same content; you choose the access.
A deck is a scroll that wants to be a codex. So is an EPUB. So is this web page.
First the book had to fit the hand.
Folded, stitched pages give random access, both sides of the sheet, and a book you can carry. In the West the codex overtook the scroll by about 400 CE. Nothing has displaced it since.
The codex won the way roads win: it was less effort. Then it became so familiar it reads as nature.
A trim size is a folded sheet.
A 25 × 38 inch sheet folded four times makes a 32-page signature of 6¼ × 9½ inch leaves. Trim it and you are holding a 6 × 9 trade paperback.
Constraints leave fossils. The size of a papermaker's sheet is still in your hands.
The furniture of the page settled early, and stayed.
One designer, Bruce Rogers, across forty years: 1895, 1915, 1935. The style swings from ornament to austerity. Title page, margins, initials, and notes in the shoulder stay put.
Page furniture is an interface. Readers know where to look before they read a word. This red note is one.
Be regular and orderly in your life like a bourgeois, so that you may be violent and original in your work.
Soyez réglé dans votre vie et ordinaire comme un bourgeois, afin d’être violent et original dans vos œuvres.
Gustave Flaubert, letter to Gertrude Tennant, 25 December 1876
Every protocol is this trade. Accept the limits of the form, and the freedom moves into the work.
Same protocol, different voices.
Interiors from the 2024 Alcuin awards and one art book. Every one keeps margins, folios and a gutter. No two look alike.
A good protocol fixes the interface and frees the content.
Read the protocol off the furniture.
A type cabinet. Each drawer: size in points, face by name, foundry number. "14 pt. Caslon Bold (No. 471)."
American foundries agreed on the point system in 1886 so that one maker's type would fit with another's.
Small protocols of the shop.
I was there, too: letterpress workshops, metal type in my hands, a page laid out one line at a time. Moving type with a trackpad has felt physical ever since.
Signature marks and catchwords at the foot of a page were instructions from the printer to the binder: fold here, this gathering comes next.
Publishing was always factory to factory.
Five trades, four handoffs. In red, what crossed the gap. Beneath it, the protocol that let it cross. Until the 1820s most books left the printer as unbound sheets.
The interfaces between trades standardized long before the machines did.
The last check before binding.
F&Gs: folded and gathered sheets. The real press sheets, folded into signatures and not yet bound: the last chance to catch a page out of order.
So meta: a protocol, published as a book, checked by a protocol.
Scale, without changing the shape.
Steam press 1814. Cloth case binding, 1820s. Linotype 1886. Penguin paperbacks 1935. Five centuries of machinery and the page barely moved. Pictured: T. Fitzwilliam & Co., printers, 1917.
A stable protocol is what lets everything around it change.
1985: the type shop lands on a desk.
Macintosh, LaserWriter, PostScript, PageMaker. I was there: fall 1986, a small publisher in California, three of us at Macs like this one, typesetting critical-thinking materials for schools.
PostScript turned the page into a program. Any printer that spoke it drew the same page.
2003: the web learns to separate content from form.
Keep content and form apart and one source can wear many designs. A heading style in a manuscript makes the same deal with a book template. Try the Aa at the foot of this page.
The rooms where the craft lived are closing.
Bookbuilders of Boston, 1937–2022, as reported by Publishers Weekly, still the trade’s paper of record. I was a member, and one year a judge of its book design awards. New York’s guild had closed the year before.
Tacit knowledge needs a carrier. If not a guild, then what?
Two thousand years of craft, written down as rules.
- Margins 1 : 1½ : 2 : 3 inner, top, outer, bottom. The big one is where the thumbs go.
- 45–75 characters a line 66 is ideal.
- Leading 120–145% of the type size; longer lines need more.
- Headings take whole lines so facing pages stay on the same grid.
- Breaks belong to what follows not to what precedes.

Domain knowledge beats coding knowledge. Whoever knows the rules can own the factory.
His factory: twenty years of writing, becoming books.
Venkat's publishing dashboard in February. Two decades of blog and newsletter archives on their way to becoming manuscripts, tracked by site, ebook and print.
Neither of us reads the code. We watch the floor, and we agree on what crosses between the two factories.
Now the factory fits on a laptop.
Two people who don't code, two factories, one shared folder and a transmittal: the author-to-compositor handoff with a machine on each side. Final manuscript to final page proofs has always taken months. Now it takes a minute — if, and only if, the mise en place is in place. The printer is still a printer; that handoff closes the talk.
The transmittal is the oldest handoff in trade publishing. Now a machine can read it.
Mise en place: what has to be ready before the factory.
- chapter titles marked
- special paragraphs marked
- images big enough to print
- front and back matter in order
- the text, edited and settled
- permissions cleared
- copyright page facts
- trim size and typeface chosen
- a cover, from a designer
Cooks get everything chopped, measured, and in a bowl before the heat gets turned on. In teal: what Inspect, the factory’s free preflight, checks for you. The book factory idea was Venkat’s; now Timber, Sachin, James and I are working out how much of the manuscript prep we can hand to the factory for the projects Protocol Institute and Monstrous Times are planning for the coming year.
The work before the factory never goes away. A protocol’s job is to say exactly what it is, and to check it for free. Structure must be earned.
One manuscript through the factory.
- Transmittalthe spec, from trim size to typeface
- Uploadone manuscript file, from whatever editor you write in
- Inspectthe preflight; run it as often as you like
- Build and downloadan EPUB and a print-ready PDF each time
The client page for Obliquities, in flight this week. It is a very tall page. Yes: a scroll. Scroll it.
The whole contract: two headings and six markers.
- Heading 1 chapter titles
- Heading 2 sub-heads
- [[quote]] [[verse]] [[epigraph]] [[code]] [[break]] [[signature]] typed at the start of a special paragraph
- Any editor then run Inspect, free, until it is quiet

The fragile step was never the editor. It was moving style definitions between documents. So the protocol shrank to names every editor already has.
Three styles to start. The constraint is the feature.
Four choices belong to the author: typeface, text size, section breaks, paragraphs. Margins, running heads and everything else follow from the trim.
How much freedom is safe? Every book tool has to answer. Start narrow, and layer in complexity as the rules prove out.
Publishers already sit somewhere between factory and craft.
Tim O'Reilly came up in this morning's panel. His covers prove a house template can carry a publishing program for decades: a template is a brand, not a compromise. Metalabel's releases are the other pole, each book its own design. The factory serves the first pole today.
A series design is a protocol the reader learns once. Constraint at the factory end is what lets a small press look like a press.
Preflight: 531 things noticed, none worth stopping for.
Inspect reads the manuscript file against a list of rules and says what won't come through the way you meant. 434 items were carried through automatically. No LLM reads the manuscript.
F&Gs, moved to the front of the line. The check costs nothing, so you run it until it is quiet.
This week the room ran the factory. Eight manuscripts, no studio in the loop.
One author made 953 markers in a manuscript and every one resolved. Another declared 21 custom styles because nothing had told them a style is only a name. Both are right: the factory takes what the room gives it, and every error becomes a better message.
A protocol is tested by strangers. The studio wrote the rules; the room found where they were wrong.
What the room taught the factory.
break; another, center. We wrote #let break into the typesetter and it stopped inside our template. Our error told them to search their manuscript.Reserved and built-in names get a prefix at build time; nothing to change on their side. Next: an error that says “ours, not yours”.[[commentary]], brackets included, as the style’s name, so the four commentary paragraphs never matched.Brackets stripped from names. Guide, template and welcome email now say it plainly: styles are names; bold and italic are buttons.verse2, verse3, break2.Verse lines coalesce into one poem block; stanza breaks hold. Next: a poetry-collection shape, poem per page.Three lines the room needed, now in the guide: footnotes are just footnotes, no marker. Math is Word’s equation editor (LaTeX accepted), native in print and MathML in the EPUB. Styles are names; bold and italic are buttons.
Every one of these was our contract being read literally by someone who trusted it. That is what a protocol is for.
The book factory is an API, and a book builds in thirty seconds.
Six HTTP calls: check the pass, upload, inspect, build, poll, download. The browser is optional. A failed build refunds itself and explains the fault in the author’s terms.
This is the factory-to-factory door. Error messages are part of the protocol: they are where the craft knowledge talks back.
The last handoff is still to a printer.
One-click print on demand is glued, not sewn, and it shows. A print-ready PDF/X can go anywhere: short-run printers like Bookmobile and Acutrack, or a broker such as Star Print Brokers for offset, printed and bound in signatures.
PDF/X keeps this handoff open: the file is not locked to one retailer’s press. Open question: should the factory teach people how to get a book printed well, too?
Postscript: how this got built.
Six months of building with a coding agent. Split view: the agent on the left, a punchlist we both maintain on the right. Robin Sloan's name for the skill: "Ask for what you want."
A punchlist is a protocol too: sections for YOU, ME and BOTH, and a fixed place for every comment to land.
Have your factory call my factory.
The book is the most pressure-tested interface we have. The form is settled. What is left to fix is the path from manuscript to that form.
What else has a two-thousand-year-old interface and a production chain ready to be written down?
