I do not want to post here, but you closed off the other thread and I have no option to send you a private message. There is a contradiction in your rules:



You state that the author or the publisher has to label a novel to be part of a series. Before that you stated that if you are in doubt you can check Wikipedia. But a Wikipedia label does not need to have an official label by either author or publisher. Anyone can do so. Authors do not always care if their novels have label or not.



I am sorry to make a hassle but I have been puzzling about the issue for some time myself and perhaps others are still in doubt too.
