A couple of months ago I wrote a free email course on indexing. It provides an overview for how to write an index, from start to finish, as well as pointers for what makes an excellent index. 

When I first announced this project, I got a few puzzled reactions. One friend commented, “That is either a great idea or you are completely undercutting yourself.” I understand what he is getting at. My work as a professional indexer depends on authors and publishers hiring me. Why give people the tools they need to avoid hiring me or another professional indexer?

This also raises the question of why pay? While I recognize that there will be a subset of authors and publishers who will not want to hire an indexer no matter what (these are some of the people I hope to reach with my course), I also believe that there are at least three good reasons for hiring a professional. These are not specific to indexing, as I also consider these factors if I need to hire an accountant, mechanic, or plumber, for example. But I think these are still worth being reminded of all the same. 

Expertise

The reason I most hear from other indexers and indexing societies is that the professional has the expertise. Most indexers have received specialized training, usually through a course, and have years of experience. This is certainly an important reason. I have been indexing books since 2011, for example, and have written over two hundred indexes. I believe that someone indexing for the first time can certainly learn, but they will not have this body of experience. Unless one plans on indexing several books, it might just be easier to hire someone than to struggle through the learning curve.

Interest

Another reason for hiring a professional, which I also think is important, is that of interest. There are many tasks that I could do, but I am just not that interested in them. Doing my own car repairs would fall in this category. Lack of interest can make a task seem tedious, and will probably make procrastination much more likely. If indexing feels like a chore, maybe delegate it instead and spend your time more productively on something else. 

Time

This leads us to what I think is the most compelling reason for hiring a professional, which is to buy time. I spend about twenty hours, on average, writing an index (length and complexity of the book are the main variables). If you hire me, you are not just buying my time, but you are also buying yourself time to do something else. Ideally, you will spend that time doing what you are an expert in, which will maximize the value that you present to the world. 

What Does Hiring an Indexer Enable?

Ultimately, the question is, what does hiring an indexer, or any other professional, enable? Yes, hiring an indexer can be expensive. You may have fears that the job will be poorly done. You may feel like you don’t have time to find an indexer. But if you did hire an indexer, what could you be doing instead? Answer this question, decide which of the two—writing the index yourself or doing that other thing—adds more value to your work, and you might have your answer for whether or not to hire a professional.
