Absolutely, Derek. We do owe a big debt to Robert Bamford and John Jarvis for their Homes of British Speedway book. It was a big undertaking and is invaluable as a reference work...but there are some errors in it. The worst is their history of Rye House, which completely misses out the building of the third and present track. And yes they do mix up Lea Bridge Stadium with Clapton Greyhound Stadium at one point in their entry and there are also minor errors in a number of other entries. This is not meant as an out and out criticism of the book. As I have said it is such a valuable reference tool in most instances, but just because something is said in Homes doesn't mean it is automatically right, though I'm sure well over 95% is correct.
As I know myself only too well, it is almost impossible to get everything right in a book!
