This book is an excellent reference work for anyone who indexes books. While Book indexing is mostly intended for indexers, I still recommend it for writers and editors.
Book indexing gives a good introduction to indexing. Importantly, it also contains sound advice for authors about how they can help create a book that is easy to index.
There is an in-depth discussion of index structure, and the arrangement of index entries. Special attention goes to indexing of names, short forms, numbers and symbols.
The book also covers the various index formats, options for layout and the editing requirements of an index. She also gives a good overview of software for indexing and other tools.
Naturally, this book contains an excellent index!
