I recently began indexing book manuscripts. I often work with authors directly, and more often than not they need an index in addition to editing. I have referred such work out to colleagues in the past, but it occurred to me that I could expand into that area relatively easily.
I’m still learning, as in all things. Exploring various software programs designed to assist the indexer. Discovering what a different mental process is required for indexing in comparison to editing or proofreading.
So far, so good. I am enjoying the work, and now have an additional skill to offer.
