I just bought a few more books. First one is Vernor Vinge's
True Names, previously advertised by me inside this topic
back in January. At that time I read it in a pdf form, but I really wanted to have it also in physical form -- and I finally have it!
The hard copy of the novel contains a huge preface (about 187 pages long), which include some essays about privacy and cryptography. The most important of these essays is Tim May's
True Nyms and Crypto Anarchy. This is itself a great reading but I couldn't find it anywhere on the Internet. If anyone finds it, feel free to share it. But I believe this essay was written especially for prefacing the book
True Names, thus there are low chances to find it on the Internet.
