History of Nigeria (1969) was first published in 1929 and completely revised by its author, and gives the history of Nigeria from before its first encounters with the British, through colonial rule, and up to independence in 1960. It describes the peoples of Nigeria and the British conquest and colonial administration, and is full of detailed and valuable information relating to trade and industry, transport, housing, land tenure, education, religion and tribal customs. Appendices feature royal genealogies and the texts of treaties.

History of the British West Indies (1954) examines the history of the islands of the Caribbean from their first discovery, through the periods of colonisation and slavery, and up to the beginnings of their status as independent nations. The actions of other nations are studied, as well as the British, as the various colonial powers vied for possession of these valuable possessions. Terrible cruelty was inflicted by colonial masters to the indigenous inhabitants, the slaves and indentured labour, and the worst of these are recorded in separate appendices.

Parliament as an Export (1966) deals with the adoption of overseas countries and particularly the Commonwealth countries of the British Parliamentary system. These countries examined are the original British colonies, the Dominions, the Indian sub-continent and the newer colonial territories.

Ada is the only ISO-standard, object-oriented, concurrent, real-time programming language. It is intended for use in large, long-lived applications where reliability and efficiency are essential, particularly real-time and embedded systems. In this book, Alan Burns and Andy Wellings give a thorough, self-contained account of how the Ada tasking model can be used to construct a wide range of concurrent and real-time systems. This is the only book that focuses on an in-depth discussion of the Ada tasking model. Following on from the authors' earlier title Concurrency in Ada, this book brings the discussion up to date to include the new Ada 2005 language and the recent advances in real-time programming techniques. It will be of value to software professionals and advanced students of programming alike: indeed every Ada programmer will find it essential reading and a primary reference work that will sit alongside the language reference manual.

Captain F J Walker, RN, did more than any other man at sea to win the Battle of the Atlantic, a vicious and unrelenting struggle which Churchill described as the dominating factor throughout World War Two. He was a formidable figure and one of the greatest fighting captains in the history of the Royal Navy, sinking twenty U-boats. For this he was awarded a CB and four DSOs, only the second man in the history of the Royal Navy to receive this award four times. A month after D-Day, exhausted by his continuous actions at sea against the enemy and his successful exertions to keep the U-boats out of the English Channel to ensure the safe passage of the Allied landings at D-day, he went ashore in Liverpool after a patrol. His ships and the men he had trained and inspired were already back at sea when he died on the 9 July, 1944, aged 48. His ships went on to sink another nine U-boats, bring his flotillas total up to twenty-nine, before the U-boat fleet finally surrendered. Fifteen of which were sunk by Walkers own ship, HMS Starling.

Ada* is unquestionably one of the most significant programming languages to emerge in the last decade. The manner of its inception and support by the US Department of Defense (DoD) ensures that it will be used extensively for the indefinite future in programming large and complex systems. The growing availability of compilers means that many organisations are already committed to using the language for sizable and significant applications. As a perhaps inevitable result of its design goals, Ada is a "large" language. It has Pascal-like control and type constructs; a mechanism for exception handling; a package structure for information hiding, decomposition and separate compilation; facilities for low-level programming; and a tasking model of concurrency. It is perhaps this last area that has generated most debate, criticism and disagreement. The purpose of this book is to review the tasking model in the light of the extensive analysis and comment which has appeared in the literature. The review is necessarily wide-ranging, including discussion of - Ada as a general purpose concurrent programming language, - Ada as a language for embedded and distributed systems, - implementation issues, with particular reference to distributed systems, - formal semantics, specification and verification, - proposed language modifications. By consolidating this discussion within the confines of a single review, potential users of the tasking facility are enabled to familiarise themselves with all the factors which may impinge upon the performance, reliability and correctness of their software. The book also provides a focus for any debate on modifications to the Ada language, or developments from it.
