An A to Z of almost everything - Trevor Montague

This extraordinary work of reference is nothing less than an A-Z of everything - from Abbreviations to Zip Codes. Painstaking in its quest for accuracy, comprehensiveness and truth, the book contains nothing gimmicky, no superfluous illustration: it is pure fact. Many of the sections stand up in their own right as reference works - e.g. the music section encompasses more information than many specialist music books, the history section contains a detailed chronology of world history with every major event being listed. The geography section includes the only fully comprehensive list of every known capital, even uninhabited Pacific islands.
