Message from our President

Sam Leith

The work the Society of Indexers does is invaluable, not only as a resource for indexers but for the publishers who employ them. It offers a fraternal and sororal support network, it provides training and accreditation, and it offers an assurance of quality in this difficult, vital and underappreciated art. An intelligently compiled and accurate index is an absolutely indispensable part of the vast majority of nonfiction books — from scholarly monographs to cookbooks, popular histories to legal texts. The SI exists to remind publishers and readers that the index isn’t an optional extra, and that a computer can’t compile it for you. And it exists to put them in touch with the professionals who can. This new website will make it easier than ever to fulfil that role.
