Richards is an important figure in textual studies. Some of his students and scholars influenced by him began the lit-crit movement called "New Criticism." Though Richards was not part of that movement, one can see how he would be lumped with that group. Richards' purpose in this book is to argue for close reading of the text, and especially to focus on "100 Great Words" (actually 108). These are words one might encounter in reading and in evaluating reading, but which have a variety of meanings. So attention to these words and what they might mean in a given author is key to understanding that author. For Richards, the stakes are high. The misuse of these words is a "prelude to oppression or surrender," and consequently discussion itself must be reconceived as he notes in the afterword to the book. The goal is to follow logic and reason, "for Reason is what gives us … freedom, and that is why it must rule." The book is a rather dry read, and Richards comes across very much as a professor with a capital P. That said, his examples (too few I feel) of close readings can serve as an example in better reading of a text, and his consideration of the "100" words is worth a look.
A misleading title this book. If you expect a book with a simple and practical examples about "how to read a page" so you can improve your reading comprehension skills, forget about that. Althought is true that other coments says, this book is more about philosofy of reading than anyting else, written in a dense maner.
I might not be able to memorize all the mentioned words in this book but it was able to make sense that my word usage and other peoples word usage can sometimes bear two different meaning even if your using the same word.
