On a first edition the price often sits in the dust jacket, in the imprint, and in a signature, not in the reading. A jacket with a tear is a different price. In the overview [Security for collectors](/artikel/sicherheit-fuer-sammler) books sit with the paper.

## What breaks without a thief

Light on the signature, damp, mold, a shelf that warps the boards, sun at the window spot. You store them upright, not in a packed row that presses the text block, dry, dark. You take the jacket by the edges and you do not lay it loose on the pile.

## When someone comes

Nobody takes a whole shelf in five minutes. The ten books with a name and a jacket do, if they stand at eye level. Those ten do not stand there. They stand inconspicuously, or they lie, when the price calls for it, in a locked cabinet, jacket protected, proof elsewhere.

## The folder

Author, title, year, printing or edition, condition of the jacket, signature yes or no, proof. A photo of the imprint, the jacket, and the signature. The policy lists the expensive volumes one by one.


## Häufige Fragen

### Take the jacket off to read?

If you keep the edition as a collector's piece, you read another copy. The jacket stays intact.

### Signed books in the light?

No. Ink fades. The permanent place is dark.

### Do ten lines cover a hundred books?

For the holding, yes. For the expensive volumes, no. Those get a line of their own.
