Telling Readers What This Thing Is

In my last post I wrote about entries and arrays, which I described as the building blocks of an index. I defined an entry as “what this thing is + where to find it.” Today I’m going to expand on “what this thing is,” also known as main headings and subheadings.

The fundamental purpose of an index is to guide readers to the relevant information that the reader is searching for. To do that, the index needs to be clearly written, which begins with the first words that the reader sees. 

Main Headings

The main heading, also known simply as the heading, kicks off the entry. This is the first word or phrase that you see in an entry and array. It is typically a noun, and should be clear and concise. If a longer phrase is needed, the main heading should lead with the most important element. The main heading should also match how the term is used in the text, such as using the same spelling and capitalization. 

The heading should be reflective of both the text and the audience. Is the book discussing cars more generally or electric vehicles specifically? Or both? Will readers be reading this book to learn about the auto industry, new innovations, or specific brands and models? Or all of the above? To give another example, biblical characters such as Matthew, Silas, and Timothy probably don’t need a gloss clarifying their identity in a work of biblical studies to clarify their identities, but these names may be more unfamiliar to readers if they appear in other disciplines. 

Another consideration is whether or not to pluralize main headings. Should it be dog or dogs? Cantaloupe or cantaloupes? To start, be mindful of differences in nuance. Freedom is somewhat different from freedoms, for example. Otherwise, I tend to follow common usage. If a term is commonly pluralized, then I go ahead and make it plural in the index, which I think reads more naturally. 

To give a few examples of main headings:

Acts (biblical book)

Cleveland, Grover

electric vehicles

heat transfer

London (ON)

trade wars, retaliatory

Subheadings

For short arrays containing a handful of locators, a main heading is usually sufficient to specify what this thing is. But more specificity is often needed for topics with extensive discussion (usually when there are more than 6-10 locators) or if there are different aspects that readers would appreciate differentiated.

The subheading is placed after the main heading. Its purpose is to further clarify what this thing is. Because subheadings often differentiate references from one another, there are usually multiple subheadings per array.

Since the subheading is appended, there is more flexibility in how it can be phrased. Depending on the context, the subheading can be either a short word or phrase, or it can be longer and more descriptive.  In all cases, the relationship between the main heading and subheading should be clear. If possible, I try to also lead with the key word, which both affects how the subheadings are alphabetically sorted and, I think, makes it easier for readers to find the subheading as they scan the array. 

For example,

Acts (biblical book): authorship; within biblical canon; commentaries on; Paul within

Cleveland, Grover: first presidency; free-silver issue; legislative achievements; private life between presidential terms; second presidency

heat transfer: conduction; convection

Effective headings and subheadings connect readers to the text. Main headings are the point at which readers encounter the index, and readers should not need to guess what this thing is. The same is true for subheadings, if the reader decides to read further into the array. 

Tell the reader what they need to know. Be specific and concise. Do this, and your index will be well on its way to being excellent.

Indexing as Storytelling

What does the process of indexing consist of?

Is it primarily a process of extracting terms from the text? I’ve noticed, when talking to readers and editors, that this seems to be how many people conceptualize writing an index. It is less writing and more data mining. 

I want to suggest an alternative approach. While identifying and picking up key words is important, I don’t think that that is enough. A excellent index should also contain an element of storytelling. 

I also want to address a mistake that I’ve seen newer indexers make. It is being so focused on the myriad details of the text that they—and the index—lose sight of the larger context. I’ve noticed this especially in subheadings. I don’t think that this is an intentional mistake. Books contain such a tsunami of information that it can be difficult to know where to focus. This is why I prefer to spread the work out over several days, so my mind has time to process and absorb what I’ve read. If you struggle to keep the big picture in mind while indexing, I hope this reflection gives you some pointers.

As a caveat, while writing this I have in mind narrative-driven books. Think histories and biographies. These are books that typically contain a lot of detail while also telling a story. Other sorts of books, such as in the social sciences, how-to guides, or law, are more technical in nature and may not have an overt narrative (though every book should have some sort of structure). But even for more technical books, it is important to keep the larger context in mind. 

Context, Context, Context

In my book, Book Indexing: A Step-by-Step Guide, I discuss what I call the hierarchy of information. At the top is the metatopic, which is what the entire book is about. Below that are the supermain discussions, which are the handful of major arguments or areas of focus that comprise the metatopic. Below the supermain discussions are the regular discussions, which are the sub-discussions which flesh out the supermains. At the very bottom are all the little details, typically names, places, events, etc… All of these layers are nested together and should be reflected in the index.

When I refer to the context or the big picture of a book, I am talking about the metatopic, supermain, and regular discussions. These are the overarching discussions that give meaning to the smaller details. Problems can arise when the indexer fails to link back to the context, leaving readers confused about the meaning or relevance of an array or subheading.

Audience as Context

Before I jump into some examples at the subheading level, which is where I usually see this issue, I also want to mention that the book’s audience is also an important context. Not every detail is indexable. Before starting the index, think about what is important to the readers.

I’ve seen it happen when the indexer is so focused on picking up the details that they forget to assess whether the details are relevant. For example (and this is a made-up example, as I don’t want to embarrass anyone), say the book is a memoir on hiking Mount Everest. The author also briefly discusses, over a few paragraphs, a previous trip hiking Mount Kilimanjaro. Since it is discussed, Mount Kilimanjaro should have a main entry, but because the overall focus of the book—and presumably of readers—is on Mount Everest, the indexer does not need to pick up specific details about people and places associated with Mount Kilimanjaro. Those details are not relevant and will bloat the index. Instead, focus the index on Mount Everest. 

Using Subheadings to Tell a Story

Now let’s discuss subheadings.

Subheadings are crucial for breaking down large arrays into searchable chunks, but they are only effective if they are clearly written. Subheadings which are too granular and disconnected from their context are not helpful.

Consider this example. This is also made-up and is similar to real arrays that I have seen.  

Obama, Barack: communications with; congressional leaders and; economy and; Iraq and; oil and; as president; Senate and

How much do you understand about Obama from these subheadings? Do you have a clear sense of what you will find if you let these subheadings direct you?

To start, who is Obama communicating with? About what? It could be about anything. The subheadings “congressional leaders and’ and “Senate and” are a little more specific. If the text itself is vague or if these subheadings cover multiple interactions, then this level of vagueness may be appropriate. But what if we learn that these three subheadings are all referring to negotiations over the Affordable Care Act? Now we have context.

“As president” is also an unhelpful subheading, since most readers should know that Obama was president. Does it help to learn that the context is being elected during the 2008 presidential election? The other subheadings, for the economy, Iraq, and oil, may be clear enough, though it again depends on what the text is actually about. 

While all of these subheadings are technically correct—Obama is indeed communicating with someone, he is president, and he is doing something in regards to the economy—these subheadings also feel disconnected from anything concrete, at least to me. If we revise these subheadings to more accurately reflect the larger discussions, we get the following array. Which seems more connected to his presidency? Which is more helpful to readers?

Obama, Barack: 2008 presidential election; Affordable Care Act; economic policies; Keystone XL pipeline; withdrawal from Iraq

Let’s look at another example. Sometimes subheadings within an array are treated as a list, as in a list of names. 

Microsoft: Allen; Ballmer; Gates; Nadella; Wallace

These are all key players in Microsoft’s history. They are important and should all have main entries, but is listing them as subheadings really the best use of the Microsoft array? It doesn’t tell us much except that these people all have links to Microsoft. Why not use the subheadings to instead tell Microsoft’s story? Gates, Ballmer, and the others can still be in the index; just not the focus here. 

Rewriting the Book in the Index?

At this point, I can imagine a couple of objections. Is storytelling really appropriate within an index?

A common rule of thumb is to not rewrite the book in the index. I understand the point, that the index is supposed to direct readers to where the discussion actually is. But the index can only direct if the entries are clearly written. One of the best ways to be clear, in my opinion, is to connect to the larger context. I enjoy stories, and so I like to think of this as storytelling. If it helps, think of this as being clear and specific. What will resonate with the reader? Use that to hook the reader and send them in the right direction. 

It is also important to select the level of specificity that matches the discussion in the text. Returning to the Obama example, the Affordable Care Act is much more specific, and therefore more meaningful, than a generic subheading for healthcare policies. But if the discussion in the book is more like a broad overview, as in an overview of various economic policies, then a subheading at a broader level, like “economic policies,” would be the better choice.

Storytelling vs. Lists

I am also not saying that you should never make a list. Using subheadings to gather information into a list is also a valid approach. The two approaches can even be used in the same index. For example, for a book about Margaret Atwood, the main array for Atwood could tell the story of her life and career while a separate array—perhaps appended using the em-dash-modified format—could list all mentions of her novels and other writings. Books that are more technical in nature, rather than narrative-driven, may also favor lists over storytelling. The trick is knowing when each strategy is appropriate.

I also think that storytelling—making sure that the big picture is adequately represented in the index—can be more difficult to do, or at least more difficult to remember. It is summarizing and pointing towards the narrative and structure that exists within the book. Gathering together a list is often easier. 

When indexing, remember that you have options for how to present entries and information to the reader, and that your goal is to clearly communicate what the book is about.

Taking a Step Back

So how do you see the big picture? How do you channel that wave of information that is threatening to overwhelm you?

I find it helps to pause and take a step back. I especially do this if I feel like I’ve lost sight of the author’s argument or point. Or if there are a lot of names and other details and so it is easier to make two passes over that section, once for the details and a second time to see the full picture. I ask myself, “What is this discussion about, anyway?” Once I’ve identified the overarching discussion, I may need to go back and create entries for the context that I’ve missed.

If you struggle to see the big picture or the hierarchy of information, try to develop a habit of pausing and reflecting. Read until you hit a transition. Pause. How would you summarize the discussion you just read? How does the discussion fit into the larger structure or narrative of the book? Try completing the following sentence: “This section is about…” Be clear, specific, and meaningful. Once you have your answer, put it in the index.

Making a Plan Before Starting an Index, How to

I found myself thinking last week about the value of making a plan before starting an index. It is something I do as part of my indexing practice. But what do I mean by making a plan? While I discuss elements of making a plan in my book (especially in the “Get Ready” section, though the whole book, really, is to help you make a plan to tackle your index), I don’t think I’ve previously pulled together what it is I mean when I am beginning an index.

So, assuming you understand the basic elements and process for writing an index, and you have received the page proofs from the client and are getting ready to start the index, how can you go about making a plan? 

For me, making a plan can be broken down into answering the following six questions.

  1. What is the book about? This question is about determining the focus and scope of the book. I read the book’s description on the publisher’s website, if available. I also read the table of contents, and maybe skim the introduction and a couple of chapters. I want to get a feel for the main topics and headings that I will be picking up. With this broad sense of the book in mind, I may also begin thinking about how to translate that into the index’s structure.
  2. Who is the audience? Beyond what the book is about, each index should be tailored to its audience. Will readers prefer a detailed index or a lighter index? Are readers picking up this book to answer a specific question or for entertainment? What does the audience already know about this topic, and what will they expect to find? Similar to determining what the book is about, considering the audience is also about focus and scope. Which details are relevant, and which irrelevant? Depending on the audience, not all details need to be picked up.
  3. How much space is available for the index? This is a question to confirm with the client. If I can have all the space that I want, then space isn’t a factor in my decision-making. If there is a strict page or line limit, then I may need to make decisions about structure or which entries to include or exclude in order to fit. Planning ahead, I may consider using fewer subheadings, for example, or to outright exclude certain categories of details to ensure that the priority entries make the cut.
  4. Does the book contain any specific indexing challenges? For example, are there a lot of illustrations? Are there legal cases that require special formatting? Are there terms from another language that contain diacritics or other special characters? Are there a host of family members that may need differentiating? It is not always possible to anticipate challenges, but if you can, now is a good time to consider your approach so you don’t get hung up partway through the index.
  5. What is the publisher’s preferred style? If you are not familiar with the publisher’s style guide, now is a good time to review. I find it helpful to get the format right from the start, such as alphabetization and locator abbreviations, so I don’t have to think about it later.
  6. What is my schedule? This is partly a question of the deadline to submit the index to the client, as well as a question of my own plan. Which days am I going to work on the index? How much am I aiming to complete each day? When do I want to finish the rough draft and when do I want to finish the final edit? 

All of these plans are, of course, contingent. It may take me longer than I expect to write the rough draft. I may discover an unexpected challenge. I may need to rethink my approach in order to keep the index short enough. Continuing to revise and refine the plan is, for better or worse, part of my indexing process.

But I find there are still benefits to thinking through all of these questions before starting. Knowing what the book is about and who the audience is helps to shape the entries I create and cuts down on irrelevant ones. The rough draft is usually a little cleaner and easier to edit. Indexing to the space available helps to avoid needing to make deep and painful cuts late in the process. Identifying challenges early means indexing correctly from the start, rather than going back to fix. Creating a schedule helps to keep me on track.

How much time should you spend making a plan? That is up to you. For many books, I only need about five or ten minutes to assess and make a plan. I may jot down a couple of notes and otherwise will keep my thoughts in my head. I’ve so far indexed around 500 books and many books are similar enough in terms of structure and genre conventions that I quickly know what to expect. Though I also work on some books that are more complicated or unique, and for those I do spend time digging into what it is I am unsure about. I am also aware of some indexers who use a checklist or form to help them prepare for each index. Find a system that works for you.

Writing an index is a constant process of decision-making. Making a plan can help streamline some of that decision-making, and provide confidence that you are setting out on the right path.
