I purchased this book as a 'set book' for an Open University course. It contains extracts from works by authors from the period covered by the book and modern historians. I found the book very interesting and informative - although best read in conjunction with the couse for which it was purchased.
Yes, it is an excellent resource, but only if used in conjunction with the text, and as this is an Open University publication, it forms part of a course. However, it will appeal to students and readers of medieval history, scientific history and the history of medicine for that period. Because of the high price, I can only give it a max. of four stars
