Emil Artin and John Tate held a seminar on class field theory at Princeton University in 1951--1952. Their notes were published in 1967 by Benjamin (New York), but the first four chapters covering (among other things) "the fundamentals of algebraic number theory" and "local class field theory" were omitted from the printed version.

**Question.** Are the notes of Chapters 1--4 available to you ?

**Request.** Can you make them electronically accessible to the mathematical community ?

**Postscript.** Parts of Hasse's *Klassenkörperbericht* (Bericht über neuere Untersuchungen und Probleme aus der Theorie der algebraischen Zahlkörper)
are available online at the Göttingen library :

Jber. deutsch. Math.-Verein.
Teil I : **35** (1926), 1--55,
Teil Ia : **36** (1927), 233--311.

Ulf Rehmann (Bielefeld) and Keith Dennis (Cornell) have promised to put Teil II (Jber. deutsch. Math.-Verein., Ergänzungsband 6 (1930), 1--204) online soon.

**Addendum.** In an interview which has appeared recently in the Notices of the AMS, Tate makes some remarks about the genesis of the Artin-Tate notes.
