It's a blog! Mainly of book reviews.
So I identified 6/100 of these photos of interesting details and views of Bath. Anything from gravestones to streetlights feature and the cityscape has changed most in these details over the last twenty years - some of these pictures are now historical records. Even in 2000 it would have been hard to identify all 100, though. Most are obscure and many are in outlying locations. "Within one mile of the Abbey," implies over three square miles to search.
The charm of the book, though, is not so much in the puzzle as in the focus on detail, which makes these pictures well out of the ordinary in terms of Bath photography - and Newland's eye and camera skills are very good.
Here's a Bath architectural detail photo I took myself:
