Is there anything more annoying that getting that book that will almost certainly be an essential part of your Works Cited/Bibliography only to discover that there is no index!? We all know that we can not read every single book we cite from cover to cover. We don’t have the time, and quite frankly, we don’t always have the patience! Therefore, when someone tells you that you should read the bits about the theme of X in Book Y it is natural to flip to the back of the book and check the index unless all the information is contained in one or two chapters. Of course, with Google Books at our fingertips it can make the search through an index-less book a bit easier. But we all know the limits of the preview. Oh, how cruel the world can be!
Quite simply, indexes speed up the research process. We cannot always rely on chapter titles, or even book titles, to tell us exactly what a given book discusses. Often, these cleverly punning chapter titles are fun to read, but give little away about their actual content. A well-stocked index can lead the researcher to the sections s/he needs while at the same time giving an overall flavour of the book and demonstrate connections between various subjects addressed within which may even lead to full cover to cover read.
Something almost as frustrating as no index at all are name indexes…..no themes, keywords or other issues….just names! That’s great if you are looking for a person, but otherwise what is the point! Therefore, not only should all academic books have indexes, but they should have fully comprehensive indexes that cover all the potential needs of the reader. Academic books are being priced more and more out of reach of many scholars. When you scrape together a week’s rent to buy that must-have new monograph or edited collection an index is at least a small and useful consolation prize.
