For much of his life, alongside his writing, Mr. Iggulden has been actively involved in a family business, Planet Lighting, the industrial engineering company started by his father in 1911.

The Iggulden papers at Thomas Cooper Library include typescript for two (unpublished) volumes of autobiography, several short autobiographical sketches, essays on monetary policy, and some unpublished poems. In addition, the archive contains correspondence with USC's Dr. Matthew J. Bruccoli and incidental material relating to Iggulden's roles as an active environmentalist, businessman, and a former Australian National Gliding Champion.

Materials in the collection have been donated by the author himself over several years. The papers provide an important key to the intersection between Iggulden's life and his various works.  The papers are supported by a collection of Iggulden's published books, donated by Professor Matthew J. Bruccoli.
