Now that you have a list of citations and their accompanying bibliographic information, what question is not relevant when evaluating the author of a source?


How reputable is the author?
Who considers the author an expert?
Is this the last book the author has published in this area?
Is this the first time the author has published in this area?

I think C is irrelevant.

The question that is not relevant when evaluating the author of a source is "Is this the first time the author has published in this area?"
