Interesting blog post at "An American Editor" blog.
It has been an ongoing frustration of mine, dealing with bibliographic information that cites the Internet and ebooks.
In the olden days, way back when I was a student, the rule was that citing a source meant it really existed and was verifiable; one couldn’t cite and have accepted “James, J. (2010, August 10). Private conversation.” But today, I guess, anything goes — at least if you are in the role of author but not in the role of paper grader; that is, I find these types of cites in academic papers knowing full well that if a student of the author submitted such a cite, it would be unacceptable.
More important, however, is that cites to web pages that no longer exist — if they ever really existed — seem to be de rigueur, and no one complains. It used to be that it was not enough to cite a source, but the source had to be reputable and accepted in the field. It was pretty hard to cite Portnoy’s Complaint as an authority on sexual mores, yet I suspect that would not be true today.
