I attended my first Le Mans 24 Hours race this year without much prior knowledge of the history of the event, or sports car racing in general. As anyone else who has been to the event can no doubt understand, I was instantly hooked and began looking for Le Mans-related books on my return to the UK. Soon I discovered this volume, the first in a series of tomes on the race's history broken down by decade.
As an introduction to each race of the decade, this book could hardly be bettered. Each race is allotted approximately thirty pages, and each report includes the full entry list and race result (in addition to other event-specific statistics). There is no single, overarching race report, but a brief summary followed by paragraphs on various important aspects of the race, usually arranged by marque or team. Thus the famous 1969 race has sections on the winning JW Automotive team, Jacky Ickx's protest against the "Le Mans start", and then the entries of the factory teams (Alpine-Renault, Ferrari, Alfa Romeo, Lola and Matra). This is very much a photographic review, with hundreds of colour and b&w images sourced from the Automobile Club de l'Ouest, and numerous other archives including the teams' own. The main body of the book is preceded by an introduction which contextualises each race within the decade as a whole, and the decade within the wider history of the event, and also contains useful technical information such as the equations used to determine the winners of the Performance Index and Thermal Efficiency Index awards, prizes almost as valuable as outright or class victory. There is also a statistical appendix which includes driver-by-driver results and other information such as fastest speed recorded during the event. I can't say how accurate all of the statistics are, as I was not previously familiar with the races, but as an official ACO book the information should be trustworthy.
To sum up, this book is an excellent introduction to people wishing to find out more about the history of the Le Mans 24 Hours. Those wishing for more detail should see if it is possible to track down the surviving individual yearbooks, or check out the official 1923-2010, three-volume history scheduled for publication later this year, which aims to show an individual photo of every entrant.
