Google book is a good research tools

I have been used google books for a year. However, I haven't found its benefit until today. I thought it is just a collections of magazine and 3rd-level books.

Today, I tried it for my literature view on "sound reverberation on perception". It does really impressive work. First, I searched the book I am reading in hard copy, "Auditory scene analysis, (Albert S. Bregman)". This book is of partly view in Google, though I and search the key words in the whole text. It helps me to quickly locate the page in the hardcopy.

Great works, google.

By a way, I notice that Bregman haven't done much research on reverberation. More related works can be found in Spatial Hearing by Jens Blauert.
