Search Engines

I tried all three alternate search engines plus Google with the search "library cats". I had just read the book "Dewey" and wanted to find out more on cats in residence at libraries. All four came up with most of the same results in slightly different orders. Most of the first sites that came up were selling something but Google gave more pages of results with better sites as I went deeper. I think all four search engines would work but Google will still be my first choice.
