As for Google, it is great, if you know how to judge sources. I am a librarian, and will admit I did not find that article. I had plugged into Google a shorter portion of that quote and came up with other articles that were NOT reliable. The one sent to me seemed to be legit, and it claimed that Chamberlain spoke those words in 1913, so that fit in with a 1914 death.
Google will not replace professional librarians, and those who say it will are probably folks who never have to rely on the research assistance of academic librarians. That said, Google is GREAT. Wish I had bought some stock at the bottom!
