Quarterly publication

La Lettre

Four times a year, the house writes to its readers. Always the same form, in four parts:

A mathematical note — a theorem, a proof, an idea, told in a few pages.

II.

An object from the catalogue — the story of one of the house's books, its making, its sources.

III.

Corrections and new editions — what has changed since the last issue.

IV.

What is coming — the publications in preparation.
