Book excerpt: Indexes are the essential search tool for genealogists, and this timely book fills a conspicuous void in the literature. Kathleen Spaltro and contributors take an in-depth look at the relationship between indexing and genealogy and explain how genealogical indexes are constructed. They offer practical advice to indexers who work with genealogical documents as well as genealogists who want to create their own indexes. Noeline Bridge's chapter on names will quickly become the definitive reference for trying to resolve questions on variants, surname changes, and foreign designations. Other chapters discuss software, form and entry, the need for standards, and the development of after-market indexes.
