Unfortunately the UK is not too well served by pigeon-related publications. There is, of course, our only fancy magazine the Feathered World where the editor, Bob Batty, is always willing to publish your articles, letters and advertisements. Further afield there is Fur and Feather, Cage and Aviary and several good papers and magazines devoted almost solely to the racing side of our hobby.
However, there are several good American magazines available on subscription as well as those from many European countries; some of the latter are in English but many are only available in the native tongue.
There are dozens of excellent European books covering virtually all aspects of individual breeds and management but these are usually only printed in German, French or Dutch. Fortunately there are some good web pages available in English that cover individual breeds.
