Infuriatingly, the collection remained in one piece until the 1920s, but then a good chunk of it was sold off to a collector. There will be some surprises. For instance, Newton doesn't seem to have a copy of Galileo's definitive physics book 'Two New Sciences'. And his library contained far more books on theology than physics. He also had a fair amount of fiction... and even some books on medals.
Along with an erudite exploration of the library's history and its various oddities, the book contains a complete catalogue of the volumes, and whether they had any oddities like markings and page turnings by Newton.
