This book provides a bibliography of a wide scope of British and Irish post-graduate theses of maritime economic and social history. Its intent is to make these informative, under-utilised texts more accessible for scholars, in response to the deep expansion of subject as a historical discipline. It aims to keep these texts, often unpublished, from lapsing into obscurity. The author takes a broad approach to the subject area, including strands more particular to science than the humanities, and history as recent as the year of publication, intending the resource to be as comprehensive as possible, and of maximum use to present and future scholars. The material is primarily gathered and cross-referenced from Roger R. Bilboul’s Restrospective Index to Theses of Great Britain and Ireland 1716-1950, the ASLIB Index, and the Institute of Historical Research of the University of London. Each entry comprises Surname, Thesis Title (truncated for length where necessary), Degree Awarded, Awarding Institution, and Date. The database comprises 2500 entries, subdivided into twenty-five sections concerning:- the shipping business and all commercial/mercantile aspects of operation; exploration, cartography, and navigation; shipping and shipbuilding technologies; docks and harbours; maritime labour; maritime medical issues; naval history, piracy, privateering; international relations; maritime law; pollution and the maritime environment; fishing; sea-port communities; culture, literature, and art; maritime economics; marine architecture; coastal planning; tourism; and off-shore oil. The sections are further subdivided by location, and a geographical index is included for ease of reference. The author assures that the majority of theses are readily accessible.
