# On-line books

Here is the directory containing the books
listed below together, in some cases,
with their TeX source files.
I am grateful to Princeton University Press for permission
to post the following books here.

This is also available in a French translation,
Théorie radicalement élémentaire des probabilités
(also in
PostScript).
I thank Thierry Delbecque for the translation and critical revision.
A Russian translation
by A. A. Ruban and S. S. Kutateladze was
published by the Sobolev Institute of Mathematics of the
Siberian Division of the RAS.
I thank Professor Kutateladze for initiating the translation project and for
sending me a pdf file for posting here.

I thank Jan Suzuki for typing the TeX file.

Some of them are temporarily withdrawn for revision.
Chapter 1. Internal Set Theory

Chapter 2. Logic and ZFC

Chapter 3. The Syntax of IST
