Japanese document appraisal master Yoshida Koichi recommends:

"This book is written in a fluent and easy-to-understand way. It is a textbook that anyone can fully explore in the field of document appraisal... Its greatest feature is that it makes good use of a variety of rich diagrams and case illustrations to describe in detail the appraisal process and the reasons for the conclusions, so that readers can understand the book in detail. It allows you to understand the reasons for the appraisal conclusion. This is a good book that is different from the teaching methods of previous document appraisal textbooks and allows you to understand it at a glance. "
