The second edition of her book, An Indexer's Guide to the Internet , was published by Information Today, Inc. in 1999, and she is currently writing Indexing Skills for Technical Communicators , which is based on the workshops she delivers to corporate clients throughout North America. Indexes are as important to your documentation as your documentation is to the product. Just as it would be difficult, if not impossible, for people to use your product without any documentation, it is equally difficult for people to use documentation without a good index.
Good indexes provide multiple entries for every useful nugget of information.
Filtering those considerations through your mind will help you select index entries that meet your readers' needs. In other words, create entries that point to information that either tells readers how to do something or provides important details. Your index entries should be both specific and concise. As you gain more experience in indexing, you will find it easier to create entries that balance being specific with being concise. You should also look for opportunities to refine, expand, and enhance your index entries.
