The Society of Indexers was formally constituted at the premises of the National Book League in the UK on 30 March 1957 by G. Norman Knight and approximately 60 other people.
He "count[ed] it as one of the achievements of the Society to have removed the intense feeling of solitude in which the indexer (of books and journals, at any rate) used to work.
It provides a distance training course in indexing leading to its qualification of Professional Member.
Initially published biannually, it moved to quarterly publication in 2008.
Publication continues as of 2022[update],[7] It is the official journal of all the indexing societies.
