About the book: year / This publication is one of a kind and unique precisely in the completeness of the material presented. It's just very hard to believe that so much can be written about proof theory. Using this book, you can not only prepare perfectly for passing the exam, but also write a dissertation, term paper, etc. I have not seen any books on proof theory that are even remotely close in their completeness to this book. The book is from 1970, and naturally a lot of attention is paid to the problem of socialism and capitalism, but this in no way detracts from its merits. The book can become a kind of example of how to write textbooks and books. Very fundamental work! This work is included in the “Best Legal Literature” project. This series was organized by me and I hope, with the help of Maxim Moshkov, to provide the opportunity to obtain literature through the Internet, which I consider the best of its kind. This project is considered open and I am ready for cooperation. Send all your suggestions to me by e-mail. Send spelled versions of these books to M. Moshkova at [email protected]. Vlad Loer.
