5. Conclusion
The breadth of coverage is indeed very wide, and those who want to delve more deeply into virtually any aspect of simultaneity will find many guideposts among the very extensive collection of references; I suspect that even most people who have worked on the subject would find some references that are both of interest and previously unknown. In short, I think most people with an interest in simultaneity, whether novice or expert, would find the book an enjoyable read.
