Adler suggests that there are three main stages for analytical reading, which can be seen in these three questions: (1) What is this book about as a whole? (2) What is being said in detail, and how? (3) Is it true? What of it?
Here are the rules. Adler occasionally restates the rule, so I've included both versions when necessary:
Stage 1: What Is the Book About as a Whole?
Rule 1. You must know what kind of book you are reading, and you should know this as early in the process as possible, preferably before you begin to read. / Classify the book according to kind and subject matter. (p. 60)Stage 2: What Is Being Said in Detail, and How?
Rule 2. State the unity of the whole book in a single sentence, or at most a few sentences (a short paragraph). State what the whole book is about with the utmost brevity. (pp. 75-76)
Rule 3. Set forth the major parts of the book, and show how these are organized into a whole, by being ordered to one another and to the unity of the whole. / Enumerate its major parts in their order and relation, and outline these parts as you have outlined the whole. (p. 76)
Rule 4. Find out what the author’s problems were. / Define the problem or problems the author has tried to solve. (p. 92)
Rule 5. Find the important words and through them come to terms with the author. / Come to terms with the author by interpreting his key words. (p. 98)Stage 3: Is It True? What of It?
Rule 6: Mark the most important sentences in a book and discover the propositions they contain. / Grasp the author's leading propositions by dealing with his most important sentences. (p. 120)
Rule 7: Locate or construct the basic arguments in the book by finding them in the connections of sentences. / Know the author's arguments, by finding them in, or constructing them out of, sequences of sentences. (p. 120)
Rule 8: Find out what the author’s solutions are. / Determine which of his problems the author has solved, and which he has not; and as to the latter, decide which the author knew he had failed to solve. (p. 135)

Rule 9: You must be able to say, with reasonable certainty, “I understand,” before you can say any one of the following things: “I agree,” or “I disagree,” or “I suspend judgment.” / Do not begin criticism until you have completed your outline and your interpretation of the book. (pp. 142-143)
Rule 10: When you disagree, do so reasonably, and not disputatiously or contentiously. (p. 145)
Rule 11: Respect the difference between knowledge and mere personal opinion, by giving reasons for any critical judgment you make. (p. 150)
