Ian Henry Publications Ltd. was established in 1975 and has published in excess of 600 books since then.
Since 1984 it has specialised in books on the history and topography of Essex and surrounding counties and is now recognised as the largest publisher of books on a single county in the country.
A further specialism of Ian Henry Publications are books based on Sir Arthur Conan Doyles Sherlock Holmes, both in pastiche form - novels, plays, television scripts - and factual titles on both Doyle himself and his creation.
Later additions to the published list include books on wellness, transport history, and, most recently and very successfully, humour.
