How To Read A Book- A Classic Guide to Intelligent Reading - Mortimer J. Adler, Charles Van Doren [17]
In this case, what you must do is skim the book, or, as some prefer to say, pre-read it. Skimming or pre-reading is the first sublevel of inspectional reading. Your main aim is to discover whether the book requires a more careful reading.
Secondly, skimming can tell you lots of other things about the book, even if you decide not to read it again with more care.
Giving a book this kind of quick once-over is a threshing process that helps you to separate the chaff from the real kernels of nourishment. You may discover that what you get from skimming is all the book is worth to you for the time being. It may never be worth more. But you will know at least what the author's main contention is, as well as what kind of book he has written, so the time you have spent looking through the book will not have been wasted.
The habit of skimming should not take much time to acquire. Here are some suggestions about how to do it.
1. LOOK AT THE TITLE PAGE AND, IF THE BOOK HAS ONE, AT
rrs PREFACE. Read each quickly. Note especially the subtitles or The Second Level of Reading: l nspectional Reading 33
other indications of the scope or aim of the book or of the author's special angle on his subject. Before completing this step you should have a good idea of the subject, and, if you wish, you may pause for a moment to place the book in the appropriate category in your mind. What pigeonhole that already contains other books does this one belong in?
2. STUDY THE TABLE OF CONTENTS to obtain a general sense of the book's structure; use it as you would a road map before taking a trip. It is astonishing how many people never even glance at a book's table of contents unless they wish to look something up in it. In fact, many authors spend a considerable amount of time in creating the table of contents, and it is sad, to think their efforts are often wasted.
It used to be a common practice, especially in expository works, but sometimes even in novels and poems, to write very full tables of contents, with the chapters or parts broken down into many subtitles indicative of the topics covered. Milton, for example, wrote more or less lengthy headings, or "Arguments," as he called them, for each book of Paradise Lost.
Gibbon published his Decline and FaU of the Roman Empire with an extensive analytical table of contents for each chapter.
Such summaries are no longer common, although occasionally you do still come across an analytical table of contents. One reason for the decline of the practice may be that people are not so likely to read tables of contents as they once were. Also, publishers have come to feel that a less revealing table of contents is more seductive than a completely frank and open one.
Readers, they feel, will be attracted to a book with more or less mysterious chapter titles-they will want to read the book to find out what the chapters are about. Even so, a table of contents can be valuable, and you should read it carefully before going on to the rest of the book.
At this point, you might turn back to the table of contents of this book, if you have not already read it. We tried to make it as full and informative as we could. Examining it should give you a good idea of what we are trying to do.

3. CHECK THE INDEX if the book has one-most expository works do. Make a quick estimate of the range of topics covered and of the kinds of books and authors referred to. When you see terms listed that seem crucial, look up at least some of the passages cited. (We will have much more to say about crucial terms in Part Two. Here you must make your judgment of their importance on the basis of your general sense of the book, as obtained from steps 1 and 2.) The passages you read may contain the crux-the point on which the book hinges-or the new departure which is the key to the author's approach and attitude.
As in the case of the table of contents, you might at this point check the index of this book. You will recognize as crucial some terms that have already been discussed.
