Cordwainer Smith / Paul M. A. Linebarger Books at AbeBooks

AbeBooks, or ABE, is an aggregate of over 13,000 booksellers in various countries, selling over 100 million books. Much like Alibris, you compare prices and bookseller's comments to find what you want.

Here are some searches I pre-made for you. Once at any given page, you can further filter by seller location (organized by country) and other factors.

This is a good way to find things in your own country. Of course, the English-speaking countries predominate, but the day I made these links, the Cordwainer Smith general search showed things in a dozen countries!

Atomskis quite pricey here compared to the Kindle book I made of it. See the image in the upper left hand corner of this page to go see it at Amazon.

Carola -- I was surprised to see quite a few copies of this here. Not cheap, but in existence.
