James,
The current edition of Anne Droyd and Century Lodge was published in the conventional way. Jessica Kingsley Publishers, while catering for a niche market (the behavioural sciences: autism, Asperger syndrome, etc), they are well known and respected in the publishing world.
The book is available at all the Amazon stores (inc Amazon.com, which caters for the United States) and Play.com based in Jersey. It can also be ordered at your local bookshop. Just quote the ISBN number, 184310282X, and they should be able to get it in for you.
Will.
