In the years since this standard work was last revised, many changes have taken place in the publishing world, not least the abandonment of the Net Book Agreement and the developments in electronic publishing. For this new edition of his invaluable guide, Michael Legat has rewritten the text extensively, not only to bring the book up to date, but also to present a clearer and more comprehensive coverage of the many aspects of its subject. Few pages of the original edition have been left unchanged, and the book has therefore been completely reset.
