These catalogs will be updated periodically. More items will be listed in the future, but sold items will drop from the list.

Many bibliographical references indicate the edition or reprint of the item in question. Its publication year appears at the start of the reference.

The material is sold at a symbolic price (to guarantee proper use of this offer).

Conditions for purchase are as follows:

1. The books are in different conditions. Most are unused. Some are used and may even contain dedications or manual glosses. Less than 1% are xerocopies or pdf files. None have any serious damage. Given that
