Relevant Logics

'This book is a real achievement! It explains the proof methods, semantical theories, and the latest results in the field, and the author puts forward his own view of relevant logic. It's constructed in such a way that it can be taught at various levels, and it's an excellent reference work as well as a fantastic teaching tool.' Edwin Mares, Victoria University of Wellington
'The author begins by promising to get the reader up to speed on relevant logic-and delivers brilliantly with his frame-based approach. Both enjoyable and illuminating.' Patrick Blackburn, Roskilde University
