Joe, your point about most direct answers to questions is well taken.I think we have had this discussion before about whether to post when you have SOME information in response to a question; then it gets much greyer.
As a librarian, I can say that answering a question is often like investigative journalism. You have to collect all the clues, or bits of information, that you can. Then you have a better idea where to look. Our collective wisdom often works synergistically to arrive at a correct answer.
