He is probablly one of the best and most recognized of authors of books on The Beatles he also wrote one called "Beatles Recording Sessions" and another one about their live shows and this book takes elements from both and combines them so at the beginning of a chapter he sums up what happened to them in that particular year and then after that he has all the performances, appearences, and recording sessions that happened that year. So all in all the book gives us a complete picture of what life was like as a member of The Beatles.
