Your non-fiction book or publication is only as good as your index. If readers can't easily find a reference they're looking for, they'll look elsewhere.
Indexing is an art . . . and a science. Good indexing makes researching effortless, an adventure rather than an exercise in frustration. A well-crafted index offers an intellectual overview of a book's contents, which is unavailable by any other means. It can make or break the success of your publication.
I offer indexes that are succinct, relational, logical and user-friendly. I can index any type of publication to the density required by your publisher or preference. Contact me to discuss your project.
Who should index a work?
The ideal indexer sees the work as a whole, understands the emphasis of the various parts and their relation to the whole, and knows, or guesses, what readers of the particular work are likely to look for and what headings they will think of. The indexer should be widely read, scrupulous in handling details, analytically minded, well acquainted with publishing practices, and capable of meeting almost impossible deadlines. ...Many authors do not have the technical skills, let alone the time, necessary to prepare a good index that meets the publisher's deadline.
