I love Google, so it was a joy to find this. I was very sceptical about what I could benefit from a book about a search engine!
It tells you about things most people don't know Google can find, including Stocks & Shares, phone numbers (reverse lookup too) and a whole load of other interesting features. Unfortunately a lot of the features only seem to work for American details, so searching for a British phone number does not work, nor does the stocks & shares information search.
The section on the Google API is very interesting too. This is only of use to software developers and probably of no use at all to anyone else. It tells you the nitty gritty of how to start using the API and gives clear examples of the syntaxs required.
I have given this book 4 stars, which is a mixture of 5 stars for software developers and 3 stars for eveyone else. For the price though, it is a pretty good book!
