This is a wonderful book. The translations by Prof. Scott-Kilvert are lively and interesting, especially for undergraduates. But the book is a pain in the neck to use because the editors have not thought it necessary to include an index. I have had to do one myself on the life of Alexander for my students who are using the book in tandem with Arrian's Campaigns of Alexander and Quintus Curtius (both of which are your books, Penguin, and both of which have indexes!).
Penguin, you have tarted up all your other books with new covers, and you have jacked up the prices accordingly, so when you get around to Alexander, who, after all, is the selling point of this eponymous tome, please include an index so that the book will become useful as well as entertaining.
