The Society of Indexers aims to promote indexing, the quality of indexes and the profession of indexing. It is a company limited by guarantee, membership of which is open to any person who is or intends to be directly involved in indexing. Members include specialist indexers in more than a hundred different subjects, from accountancy to zoology.
Founded in 1957, the Society is the only autonomous professional body for indexers in the United Kingdom and Ireland. It is associated with indexing organizations in Australia, Canada, China, Southern Africa and the United States of America. It was an Organization in Liaison with the Chartered Institute of Library and Information Professionals.
The Society has close links with the Society for Editors and Proofreaders (SfEP). You can read about our shared history in this document, which was prepared for the first joint conference of the two societies.
The Society has its own training course, offering a thorough grounding in the principles and practice of indexing, and leading to the status of Accredited Indexer. Criteria are stringent, and those completing the course are deemed to be competent in all aspects of indexing assessed during the training; they are designated Professional Members of the Society of Indexers (MSocInd).
Highly experienced indexers may also qualify as Accredited Indexers through an abbreviated testing procedure based on the SI course. Details available here.
After further experience, members may apply for Advanced status (MSoc Ind(Adv)), while the status of Fellow may be attained by those whose experience and competence has been approved by the Society's fellowship assessment procedure.
The Society also organizes conferences and seminars, produces a directory, Indexers Available, and publishes an international journal, The Indexer, and a members’ newsletter, SIdelights. The Society also operates a moderated email discussion list, SIdeline.
