Rotovision is a British publisher that produces several really good books on photography. 

I just got one of the latest releases in their “The World’s Top Photographers’ Workshops” series titled Travel & Nature. The book is divided into ten sections each based around a particular photographer. Each section has an interview with the photographer, several pages of their best photographs and then a Tips for Success page where the photographer gives 10 nuggets of wisdom (or common sense). 

Travel photography is a bit like ecology  in that it is a blend of several different disciplines. This book therefore has interviews with a wide range of photographers including Steve Bloom (nature), David Doubliet (underwater) and Lee Frost (landscape). 

I have most of the titles in the series, some of which are better than others. Travel & Nature due to its diversity is a great book by itself, and if you like the informative style that delves more into the mindset of the photographer rather than the equipment he or she is using it deserves its space on the bookshelf.
