Some colleagues here at the University of Michigan Libraries did a quick Facebook survey in which they asked (through Facebook's polling tool) 200 people in the University of Michigan Facebook network this question: "What is your preferred method for getting research help from a librarian?"

A tiny fraction (1%) of respondents expressed interest in contacting a librarian through Facebook. A larger, but still small, minority (19%) said they did not want to contact a librarian at all. In-person contact was the largest vote-getter with 59%.
