Books are an excellent source of thorough investigation on a given topic. But, they do not have to be read cover-to-cover in order to be used in research. You can use the Table of Contents and the Index to help you quickly determine if the book holds relevant information. You can also read the Preface or Introduction to get an idea of the scope and purpose of the book. If there is a Bibliography, you might be able to find other relevant books and articles.
