Noeline Bridge has gathered together a most accomplished group of contributors. In the opening chapter, preceding the first section, she outlines the seven problems involved with indexing names. A useful list to keep in mind to make sure nothing important has been omitted.
1 Choice of initial element
2 Length or brevity of a name: How much to include/exclude
3 One-word names: when and how to add detail
4 Distinguishing between people with similar names
5 Variant names borne by one person, including changes of name
6 Transliteration and Romanization of names
7 Names as phrases.
Half the book is devoted to language issues, roughly divided between European and Asian languages, but including a chapter, by Kate Mertes, on classical and medieval names.
