Google etc. searching

It seems that repeating searches (this is Montesquie Volvestre in France) in different search engines brings the same results; and there is a Googleopoly! In Exalead, which I really liked for its clear screens and the drop down menus, the ads are provided by Google.

All applications/vendors will follow the same general trends and bring out new features as they are created/developed/marketed.As users we will always have our own preferences regarding style, navigation, ease of use etc. and then as we become familiar with the options we become more efficient at searching. Using Google by default is reasonable in the Library setting. What is important is that we read the screens and follow the links and prompts to get the best out of any resource. And also that we keep up to date with new offerings (eg Wolfram Alpha, Google Squared) although their usefulness may only become apparent after some time.
