He starts by explaining what a regular Google search (as the most popular and search engine) is good at and what it is not. He also shows you some tips to improve Google’s ability to find what you are really looking for. He also emphasizes that while Google may be the best place to start a search it is not the best place to end it.
He shares websites that let you tap into the knowledge on the “deep web” or many websites and databases that have reliable information available but that will not be found by a Google search.
In spite of having attended several training sessions on the deep web, MacLeod’s book has some that I had never heard of before. He also had some tips for searching Google that I was unaware of such as how to limit your search by country of origin of the website.
