Message from our President

Sam Leith

Sam Leith Honorary President of the Society of IndexersAn intelligently compiled and accurate index is an absolutely indispensable part of a nonfiction book — from scholarly monographs to cookbooks, popular histories to legal texts.

The Society of Indexers is the gold standard for professional indexing. For authors and publishers seeking an index, it offers the absolute certainty of a high-quality job by an experienced and accredited professional. For indexers and aspiring indexers, it offers a support network and resources, and provides training and accreditation in this difficult, vital and underappreciated art.  

The SI exists to remind publishers, authors and readers that the index isn’t an optional extra, that a computer can’t compile it for you, and that “just doing it yourself” isn’t nearly as easy as it sounds. It exists to put them in touch with the professionals who can.
