- A good deal has been written about Second World War coastal defences and the following should be seen as an introductory guide. Most of the material listed below is easily accessible.
- For those looking for an introduction to the subject then a good place to start is B. Lowry (ed.) Twentieth-Century Defences in Britain: An Introductory Handbook (CBA, York, 1995), which is an excellent Council for British Archaeology publication with drawings and commentaries on a variety of defensive structures.
- The best single volume book with a discussion of coastal defences is M. Osborne, Defending Britain: Twentieth-Century Military Structures in the Landscape (Stroud, 2004). One of the most detailed discussions of the subject is to be found in W. Foot, Beaches, Fields, Streets and Hills: The Anti-Invasion Landscapes of England, 1940 (Council for British Archaeology, Research Report No.144, 2006). This volume can be difficult to obtain, but details can be found on the Council for British Archaeology website. Those interested in pillboxes will probably find all they want in M. Osborne, Pillboxes of Britain and Ireland (Stroud, 2008).
- Those searching out coastal defences in Suffolk are particularly fortunate as two books provide a great deal of information: C. Hegarty and S. Newsome, Suffolk's Defended Shore: Coastal Fortifications from the Air (English Heritage, 2007) deals with defences in Suffolk from prehistory to the Cold War, while M. Osborne with A. Graham Kerr, Twentieth-Century Defences in Britain: Suffolk (Market Deeping, 2008) discusses in detail the Second World War defences in the county.
