The Birdcage books of Victor Canning was the topic I chose on the TV Quiz Show Mastermind on 9 November 2009. Here are the specialist questions set, of which there was time for only the first twelve, on which I scored eleven.
Victor Canning is included on "Nigel Balchin's Contemporaries", part of an excellent web site about Balchin managed by Derek Collett.
I have created entries for Canning in The Literary Encylopedia and Wikipedia.
The well-known literary agency Curtis Brown handle the rights to Canning's work.
An audio book of Canning's 1936 travel book, Everyman's England, read by Charles Collingwood, has been published by Crimson Cats Audio Books (click on this link for details).

The widest selection of secondhand books is probably to be found on the ABE (Advanced Book Exchange) site, which includes many professional and amateur dealers.
The Amazon site is a good source for new and, through its Market Place section, second-hand books.
For professional second-hand book dealers, another very good site is Bookfinder.
