Reddit mentions of The Annals of London

This Amazon page offers an "About the Author" section that provides the following information:

• In addition to The Annals John Richardson has written a social history of London as well as histories of Covent Garden, Camden Town, Hampstead, Islington, Highgate and Kentish Town.
  
  
• He participated in founding the London Arts Board.

  A review from Reed Business Information (on the same web page) describes Mr. Richardson as an "historian, writer, lecturer, publisher, and borough politician."
  
  Though the web doesn't seem to reveal much more, you could try seeking further information from Mr. Richardson directly by writing to him through Historical Publications, a publishing house he founded. His e-mail address is available on the company's web site.
