British historians, political junkies, and trivia fans will all be delighted by the information provided in this wonderful book. The introductory material is clear, concise, and helpful for all, whatever one's level of knowledge of the British political system. The bulk of the book consists of biographical entries on each of the prime ministers. Details include a portrait, personal and family information, a summary of the political career, quotations, and the location of paintings, sculptures, and other memorials. The amazingly complete information includes some 1995 data. By coincidence, former PM Charles Wilson's death occurred the day the book was received for review. The book has nearly 100 comparative charts that highlight diverse facts from zodiac signs to maiden speeches in Parliament. The information included is almost overwhelming (e.g., one prime minister was born in Canada, more prime ministers were born Wednesday and more died Tuesday than on any other days), and this information is not in the miscellany section, either. Researchers will find helpful the brief bibliographies of works about the prime ministers (and by them, in some instances). The location of each prime minister's personal papers is noted. Recommended for all libraries at all levels.
