One of the institute's principal activities is the publication of the Archaeological Journal, an annual peer-reviewed journal containing reports of archaeological and architectural survey and fieldwork on sites and monuments of all periods, and syntheses and overviews of similar work throughout the British Isles.

A programme of monthly lectures is held from October to May at the premises of the Society of Antiquaries of London at Burlington House.
