This interesting tidbit crossed my desk recently: The Google Gap
Your search results are only as good as your query. As any of our Reference staff can tell you, people still need help finding answers to their questions. If anything, the sheer volume of readily accessible information can make searching more difficult. Your answer can be buried deep if you can't refine search results! That's where librarians' skills are invaluable - they not only know where to search, they are experts on how to search.
I have the statistics to prove it: in the last 10 years, reference questions answered at the Library are up 145%, over 54,000 questions last year.
