Penguin Collectors Society

The Penguin Collectors Society holds occasional study days, and from these we publish books based on the main talks given during the day, and supplemented by further relevant essays. This most recent study day, held at the University of Bristol at the end of 2010 looked at the history of Puffin Book...

The quick answer:Generally anything with the word Penguin, Puffin or Pelican is a book published by Penguin; there are several different series within each of these brands. In addition the names Porpoise, Ptarmigan and Peregrine are also published by Penguin.

This is indeed a frequent question. The short answer is probably not. The main reason for this is that most titles were printed in very large numbers – often in editions of 30,000 to 50,000 - and it takes scarcity to create value.
