The Middle Game of Go
Published 1971 by Ishi Press. It consists of four very detailed game analyses of games by the author, Sakata Eio, based on booklets prepared by a Japanese go magazine.
These are middle game analyses, the openings having been discussed in Modern Joseki and Fuseki.
This book launched the idea of middlegame joseki in the occidental literature, which was something of a mixed blessing.
This was supposed to be volume 1 of a series, but no more volumes were published.
BramGo (4k): This book is packed with diagrams. Each variation has a short title and about 3 lines of text per diagram. Useful book, do not expect to read it out in just a couple of days. It's a hard one and I needed a lot of motivation to read through this book.

Page 31, diagram 4 "(Consistent) However, when white plays (o), black can play the narabi of 1 reinforcing the cutting point at A and at the same time emphasizing the moyo on the right side. However, on the other hand, white can play kikashi with 3 and for black to have to answer at 4 will be rather painful for him."
My point is the book is from the early era of Japanese-to-English go literature, originally published by Ishi Press. Explanations are 80% common English and 20% esoteric Japanese go terminology. If you don't already know twenty of the more common Japanese terms for placements, attacks, and general relationships between stones, you will want to copy the glossary and stick it up someplace for easy reference.
