Dan,
I am familiar with Tom Jarret's book. He did a very nice job. It's a good general history of St Andrews and TOC. From memory, I think his book has a small section on the changes to TOC. Mine is a more specific and in depth look at how TOC changed physically, when and why (with lost of pictures, plans and photos). I do not consider myself an 'author'. My book was a personal research project that I was badgered into publishing. For people who like details, and TOC, it seems to have hit the spot.
Thanks again to all those people who have bought it. Most copies have been sold.
