Build it

Rp 59,000

Half of each ruled page here is set at 7.14 millimetres, twenty-four lines; the other half is left with nothing on it. That split is the entire specification, stated here rather than left for the parcel to reveal.

The ruled half is drawn as vector lines rather than a repeated bitmap tile, so it does not go soft when a page is scanned and enlarged, or printed at a size the file was never rendered at. One hundred and ten pages carry the two rulings the book is built from between them, split pages and fully lined ones at college pitch.

Nothing about the blank half is instructive. It is blank because printing a fixed use for it would have been a guess, and a guess is not a measurement.

In every book

The same six pages open every book: your details, who to call, the signs to point at when you have no shared language, and the map. They sit at the front because the moment you need them is not the moment to be flicking through.

This book belongs to
One page for your name and number, so a book that goes missing can come back.
My details
Blood group, allergies, who to call. Written once, carried everywhere.
Emergency numbers
Forty countries, taken from Wikidata property P2852 (CC0), agreed across two sources, every row carrying its QID. Numbers change and a book does not — verify locally on arrival.
Point at this
A pictogram grid captioned in English above and Indonesian below, for when there is no shared language.
World map
Natural Earth 110m, public domain, equirectangular, with UTC hour meridians computed from the projection rather than from a timezone database. For orientation and for pointing at, not a navigation chart.
Conversion tables
Computed from definitions — 25.4 mm to the inch — and not copied from anywhere, so every row can be checked by anyone holding the book.
Pen test leaf
The last page, printed for it on purpose. Every notebook is used this way; printing it deliberately is cheaper than losing the last leaf to it by accident.

The film

Page by page

A vertical film, 52 seconds: the cover, the ruling page, then 5 reference pages. Synthesised ambient bed, no dialogue — captions in three languages.

A vertical film from our own bench — this page contacts nobody's server to play it, and downloads nothing until you press play.

What is inside this book?

Five pages from the Sketch and Rule Notebook shown as cards: cover, divider, a split blank-and-ruled page, a lined notes page, and a conversion table page.
Five pages from the print file: the cover, a section divider, a split page with its blank and ruled halves, a fully lined page, and the conversion table. The line dividing the two halves sits at the same height on every split page in the book.

Questions

What is the ruled half's pitch?

7.14 millimetres, twenty-four lines.

How big is it?

A5, 148 x 210 mm, 120 pages, 6.86 mm across the spine.

Is the ruling printed as a bitmap?

No. It is drawn as vector lines, so it stays sharp at any zoom.

Is every page split?

Most are. A run of fully lined pages at college pitch closes the book for anything a split page does not hold.

Is it dated?

No.

Remember that all is but opinion, and all opinion depends of the mind.
