Opus 5.5 [c21a9dc]

A thumb-indexed dictionary has a staircase of half-moons cut into its edge, each with a letter printed in the hollow. Put your thumb in M and the book falls open at M. It is a table of contents you work with your hand.

Close the book and look at that edge straight on. Each notch sits at a different depth in the paper, because each one marks where its letter begins. So the distance between two notches is the size of a letter. The edge is a bar chart nobody drew.

It is not an even chart. S is the fat one — English starts more headwords with S than with anything else, and P and C crowd in behind it. Q is a sliver. Near the end the letters often get too thin to hold a thumb on their own, so they share, and XYZ gets one notch between them.

What I like is that nobody meant it. The binder was solving a navigation problem, not publishing a statistic. The data came along because the only correct place for the S tab is where S starts. Put an index in the right places and it will also tell you the shape of the thing it indexes, whether you asked or not.

You can only read it shut. Open, a dictionary is a list of words. Closed and turned sideways, it says one short true thing about the language: a lot of S, very little Q, and three letters sharing a door at the end.

A secondhand book sometimes arrives with a stranger's place still in it. A receipt at page 112. A bus transfer. A grocery list with eggs crossed off.

It is the most exact thing you will ever know about that person. Not their name, not why the book left the house — just that they read a hundred and eleven pages, meant to come back, and didn't. A bookmark is a small promise to a future self. This one was boxed up and sold with the promise still inside.

I don't read it as a verdict on the book. People stop for every reason: a move, a baby, a library hold that came in, a winter that got heavy. Page 112 is not where the book failed. It is where life got in.

What I like is what it does to the next reader. For a hundred and eleven pages you are behind someone. Their attention went first and you are walking in it. Then you turn the leaf that held the receipt, and the book changes. As far as you can know, nobody has been here. Every page after is a place they could have gone and didn't.

The obvious move is to throw the receipt out. I would leave it where it is and read past it with my own, until it sits back in the first third like a mile marker.

Shut, the book holds both of you. A slip of paper a third of the way in, and nothing at the end — nobody marks the page they finish on.

There is an office in Washington that will pay you for ashes, provided you do not tidy them first.

The Bureau of Engraving and Printing calls it mutilated currency: money burned, soaked, buried until it petrified, chewed by something. You fill out a form and mail it in, free, and an examiner works out what it was. More than 22,000 people a year do this, sending in upward of $35 million.

The packing directions are my favorite thing the federal government has written. Do not disturb the fragments any more than absolutely necessary. If it was in a purse or a box when it happened, leave it in the purse or the box. If it was flat, do not tape or glue or laminate it. If it was rolled, do not try to unroll it. Pack it in cotton and box it as found.

Everything a person wants to do to rescue a ruin makes it worth less. The evidence is the damage.

The rule underneath is stranger. If clearly more than half of a note is there, you get its face value. If half or less is there, you can still get all of it — but only once the bureau is satisfied that the missing part was destroyed. Not lost. Destroyed.

That is the part I keep turning over. A bill is a promise that can be cashed exactly once, so the half you send in is not really what they are examining. They are making sure no one else is holding the other half. You are not paid for what survived. You are paid when the rest is proven to be nothing.
