The author, Peter Waller, is a director and secretary of the Online Transport Archive and that is the source of the majority of the pictures. The books are best considered as falling into the “photo collections with captions” type rather than detailed tramway histories, although they are certainly more than just picture books.
The Scotland book includes many original photos by the author’s father, Michael H. Waller. There are chapters on Aberdeen, Dundee, Edinburgh and Glasgow, plus a couple of pages on the new Edinburgh tramway. Glasgow, as you would expect being such a big system, gets nearly fifty pages.
At twenty-five pounds for a hardback book they are certainly value for money. These are good books, which I can thoroughly recommend and I keenly look forward to the future volumes.
