It is not too often that I have the privilege of indexing an entire series. It is also not every index in which structure plays such a prominent role. I mean, structure—deciding which entries and arrays to create, where to place them within the index, and how they relate to each other—is always important, but for some indexes structure can play a heightened role.

I recently indexed the fifth volume in the Alpha Wolves of Yellowstone series, written by Rick McIntyre and published by Greystone Books. Rick has been observing and studying the wolves at Yellowstone National Park for about 25 years. His books are an intimate portrayal of the lives of the wolves, beginning with the first generation that was reintroduced into Yellowstone and continuing up to the present day. Each book typically focuses on one or two key individuals, and from there explores the dynamics within packs, between packs, and the role that wolves play within the Yellowstone ecosystem. I indexed the first volume, The Rise of Wolf 8, in 2019, and the latest volume, Thinking Like a Wolf, will be released later this year.

I highly recommend the series if you are interested in wolves, Yellowstone, or animal conservation. My Grandpa even enjoyed the first couple of volumes, when he was still able to read. I remember visiting and discovering the books in his home. He was pleasantly surprised to learn that I had indexed them, though to be honest, I don’t know if Grandpa ever fully understood what it is I do.

Indexing Wolves

From an indexing standpoint, the books present an interesting puzzle. The focus is squarely on the lives of the wolves, though with a few dozen wolves discussed and mentioned in each book, it can be difficult to remember which is which. Most of the wolves are radio collared and assigned a number (wolf 8, wolf 480, wolf 996, etc…). While the numbers make it easier to differentiate, they can also be difficult to remember. There are also a few wolves without radio collars who are referred to by nicknames, such as Big Blaze, Medium Gray, and Slant.

Another challenge is that while the author does an excellent job of weaving a narrative, there are also a lot of elements in the lives of the wolves that are repetitive. The wolves grow up, they find mates, they raise pups, they hunt, and the next year, if they survive, they do it all over again. They also frequently interact with other packs and other animals, such as bison. Each book typically spans several years, following the lives of the featured wolves. How best to index all of that without making the index too repetitive?

Both of these challenges have to do with structuring the index, which proved to be the biggest challenge. The structure should be meaningful to the subject matter and easy to use. Though once I figured out my approach, I used the same approach across all volumes. For a series, it helps to have the same indexer throughout to maintain consistency, so that readers know what to expect in each subsequent volume. 

In this index profile, I am going to outline how I approached the structure, using examples from the third volume in the series, The Redemption of Wolf 302, which was published in 2021. 

Placing Wolves in Context

As I mentioned, it can be difficult to remember which wolf is which. It can also be difficult to remember which wolf is part of which pack. So, I decided to use the em-dash-modified format to place all of the wolves together within their respective packs.

The value of this approach is that it keeps each pack together. Readers only need to look in one place to see all of the details about that pack. The downside is that this can lead to large arrays. One of the largest in The Redemption of Wolf 302 is for the Slough Creek pack, with 36 subheadings under the main heading and 16 members listed using em dashes.

To give a shorter example, here is the main heading and 4 of the 11 wolves listed under the Agate Creek pack:

Agate Creek wolf pack: background, xxii; Blacktail pack formation and, 200, 201–2; breeding, 108, 160, 207–8; confrontation with Druid Peak pack, 20–22; confrontations with Slough Creek pack, 35, 96; grizzly encounter, 135; humans encounter, 136–37; injured pup, 158, 165; membership changes, 214; pup rearing, 136; size, 23, 206–7; Slough Creek pack’s territory and, 139; visits between related females from other packs, 218; wolf 302’s interest in females, 162

—Big Blaze (alpha male), 197, 201, 206, 208, 209, 214

—wolf 06: introduction, 85, 92, 141; Blacktail pack and, 200–201, 208–11; future of, 245; hunting abilities, 211; independent living, 214, 220; interest in wolf 302, 163; photographs, plate 7, plate 8; relationship with sister, 136; return to Agate pack, 207–8

—wolf 471. See under Lava Creek wolf pack

—wolf 472 (alpha female): avoidance of Slough Creek pack, 35; breeding, 108, 160, 207–8; confrontation with Druid Peak pack, 21; disturbance from humans, 137; pregnancies and pups, 85, 92–93, 135, 214; relationship with wolf 113, 106–7

Individuals vs. Packs

Using this structure, I also differentiate between discussions about the pack as a whole and discussions about the individual members within that pack. In the example above, the initial set of subheadings under the “Agate Creek wolf pack” main heading are about the pack as a whole. Those discussions generally involve multiple members of the pack or, in the case of the injured pup, an unnamed member. Those subheadings also provide an overview of the pack’s activities.

Specific discussions and mentions about each member are found under each specific wolf. There is some overlap between the pack-level subheadings and the specific members. For example, under the alpha female wolf 472, the subheadings for “breeding” and “confrontation with Druid Peak pack” are also under “Agate Creek wolf pack.” This reflects the fact that pack-level activities involve specific wolves, which are often mentioned, and so double-posting is necessary. Though I also try to honor this distinction between pack and individuals, and not everything needs to be double-posted. 

Directing Readers

With so many wolves, and with the wolves indexed under their respective packs, it is also important to clearly direct readers to where the wolves can be found. I’ve done this in two ways.

One, all of the wolves are listed (not double-posted) as a main entry with a cross-reference to their respective pack. With 45 numbered wolves in this volume, this makes for a very long list of cross-references in the W section of the index. While it looks awkward, I think it is the clearest way to direct readers. For example,

Big Blaze. See under Agate Creek wolf pack

wolf 21. See under Druid Peak wolf pack

wolf 629. See under Slough Creek wolf pack

Two, some of the wolves leave their birth packs and either join a different pack or help establish a new pack. Some wolves move multiple times. For these wolves, I also include cross-references from their former packs to their new pack. For example,

Agate Creek wolf pack

—wolf 590. See under Slough Creek wolf pack

—wolf 642. See under Blacktail wolf pack

I chose not to double-post the wolves because I think the wolves make the most sense within the contexts of their packs. I want readers to be able to see the full picture. With so many wolves, I think it also helps readers if the wolves are handled consistently, so readers come to expect that the wolves will always be in a certain place. Also, with such a long list of wolves in the W section, I think that list is easier to scan if they are all cross-references, instead of cross-references mixed with page numbers.

Labeling the Alphas

To further differentiate the wolves, especially the leaders, I also decided to use glosses to label the alpha males and females. These wolves tend to be discussed more, and I thought a gloss would help readers identify them more easily. For example, under the Blacktail pack:

Blacktail wolf pack

—Big Brown (alpha male): as beta male, 207; Blacktail pack formation and, 206, 215; breeding, 203, 208, 209; mention, 218; name, 201; as new alpha male, 241; pup rearing, 228

—wolf 693 (alpha female): introduction, 92; aggression against sister, 136, 200, 211; Blacktail pack formation and, 201, 215; breeding, 203, 207, 208–9, 212; denning, 218; photograph, plate 8; pup rearing, 219, 222, 224, 225, 227; in Quadrant pack’s territory, 235, 236, 238, 241; relationship with wolf 302, 214, 237; unpopularity, 216

Indexing Repetitive Elements

As I also mentioned, one of the challenges of indexing these books is that wolves tend to do the same sorts of things throughout their lives. If all goes well, the wolves will breed and raise a new litter of pups every year. The wolves also hunt, encounter other animals, and interact, sometimes aggressively, with other packs.

I decided that it did not make sense to organize the arrays chronologically, as in a new subheading for each litter of pups. That would greatly lengthen the index and make it more difficult to read. Instead, I decided to gather like happenings together, regardless of year or the number of times it happened. For example, under Agate Creek’s wolf 472, above, I include all references to her pregnancies and pups into one subheading. 

I also use similar wording for subheadings throughout the arrays. As seen for the Agate Creek pack, above, I have subheadings for “confrontation with Druid Peak pack” and “confrontation with Slough Creek pack,” as well as “grizzly encounter” and “humans encounter.” This helps to signal to readers that something similar is happening in each subheading, and it helps to keep double-posts, such as under the Druid Peak and Slough Creek packs, consistent throughout the index. 

To give another example, elk are among wolves’ preferred prey, with the book describing multiple hunts. In the array for elk, I differentiate the hunts by pack and by wolves, which are also double-posted under those packs and wolves.

elk: breeding season and, 65; calves, 222; conflict between packs over, 22, 98, 202; hunting by Druid Peak pack, 38, 88, 112, 141, 142, 143–44, 149, 151, 163–64, 176–77, 179–80, 185–86, 222, plate 4; hunting by Slough Creek pack, 16–17, 45, 53, 57, 120–21, 127–28, 165, 176–77, 191, 195; hunting by wolf 06, 211; hunting success rate, 185; injuries from, 180–84; near den sites, 41, 187–88; scabies, 149–50; shortage of, 217; wolf 302’s fear of carcasses, 112–13

 

When structuring an index, every entry has its place. 

This is especially true for the books in the Alpha Wolves of Yellowstone series. Containing a lot of wolves, and a lot of details about wolves being wolves, the index entries needed to be structured in a way that made sense for the subject matter and was easy for readers to navigate. 

I hope I have accomplished that with my approach. While every index has a structure, I needed to think more deeply and be more creative in my approach for this series. I also hope that these examples give you some ideas for what is possible and for how to approach a book with unusual needs.
