Great post-and reminded me, again, of something I learned in one of my college jobs.
I worked in the Government Depository section of the university library, which is where all the GPO (Gov't Printing Office) are sent for reference and filing. This included UN documents, military training manuals, etc. People used this section of the library for all kinds of research.
What I learned is that if the researcher didn't know how to frame the questions they had, the librarians had a much harder time finding the relevant documents or sections of the library. A good librarian who could help the researcher frame the question, or define more clearly what their research purpose was, was absolutely key to successful research. Many researchers had to learn how to ask the right questions in order to get where they wanted to go-but sometimes they didn't know where that was! That learning has been a large part of my facilitation and nonprofit practice, and was a key part of my education at school.
