A good rule of thumb for deciding what to index, said freelance indexer Kay Banning, is to ask: “Is the user happy to be there when you send them there?” The answer to that question, said Banning, will help determine what to index and what not to index.
Banning said she charges usually charges $3.25 to $3.50 per page, subtracting any pages that don’t need indexing. After receiving the hard copy pages by express mail, she said she does a first read-through of the book to see the “big picture.” Then she reads the introduction and review questions to get the author’s slant for what is important in the book.
