No. A secret source is not a criterion in your definition. The only criterion is that they gather, collate, or publish information in any media. That is your definition, and that big book is a collection of information.
You may not think it's relevant to what you think of as journalism, but in the definition you have.... I even suggest Conrad Black and Don Cherry. If Don Cherry seeks to provide, on a television program, hockey statistics about how many goals, and he does this regularly, it seems to me that within your definition in electronic media he is a journalist because he gathers information and makes it known.
Thank you.
