Indexing Books as a Career: a free, self-paced online course by Sylvia Coates

This course provides basic information on writing back-of-the-book indexes and working as a professional indexer. It is not intended to substitute for a comprehensive indexing course but is appropriate for individuals wanting to explore indexing as a career. This course will also inform both editors and self-publishing authors by providing an overview of the process of indexing and working with indexers.
