The New Penguin Encyclopedia forms an integral part of Penguin's ever-expanding reference publishing programme. Edited by David Crystal, without doubt the UK's most widely respected reference editor, it offers more information and detail than any other comparable British encyclopedia. Its authoritative coverage runs from Aachen to Zygote, with thousands of articles on all branches of human knowledge. In all, it contains nearly 2 million words of text and numerous charts and diagrams. Much of the Encyclopedia was formerly published by CUP as the Cambridge Encyclopedia. Penguin have now acquired exclusive print rights to this ultimate work of reference.
