Why we organize

We organize because we need to retrieve.

-- Arlene G. Taylor, The Organization of Information (Westport, Conn. : Libraries Unlimited, 2004), pg. 1.

Leaving aside the folks who organize because of OCD…

Is there a good study out there about the range of ways that library patrons use to retrieve? Librarians organize for patrons, yet it seems to me that we rarely talk about how those patrons approach the task of retrieving, and whether our methods of organizing serve their ways of retrieving.
