These guides, so beautiful to have and to behold, mark a huge advance on their predecessors. I find them essential supplements, not only to ENO and Royal Opera programmes, but to recordings issued on CD which often come without scholarly documentation and a libretto. The performance histories – of which I wrote one myself – are especially valuable, and not easily accessible elsewhere.

Hugh Canning of The Sunday Times

For anyone with a keen interest in opera, whatever their level of knowledge, this series remains a benchmark of quality and clarity. The content is serious, reliable and trustworthy, handsomely put together, full of variety and scholarship but always making the practical experience of going to the opera a priority. I return to these volumes again and again and find the updated and new issues absolutely invaluable.

Fiona Maddocks of The Observer

This uniformly excellent series is indispensable for the serious opera lover, all the more so now that almost all the CD companies have abandoned issuing a libretto with their opera releases, and have such scant background information. The English translations are on facing pages with the original texts, and in all respects the books are helpful and compact, and interestingly illustrated.

Michael Tanner of The Spectator

I am delighted to see the return of the ENO Opera Guides, bigger and even more authoritative than before. There are authoritative new articles as well as several of the irreplaceable originals, the presentation is very handsome and a decided gain is the brilliantly chosen selection of production images, in colour as well as black and white. The Guides are an invaluable reference for opera lovers at any level.
