Google's Advanced Search: Right next to the basic Search box, click "Advanced Search" to refine your search by file type, results per page, search within a site or domain, language, etc. At the bottom of the first Advanced Search options, click on Date, usage rights, numeric range, and more to bring up additional advanced search criteria like date range of searches, usage rights like whether a document might be licensed for free use, sharable use, or commercial use, as well as Region of your search, SafeSearch (on or off), and even where the key words will show up on the Web pages you search. How many of you have ever dug deep into these advanced search options?
Google Book Search (books.google.com): Helps you find what you're looking for inside of a book and shows you where you can find that book in a bookstore or library.
--Full View Books are "complete" books in the public domain (or non-copyrighted, or shared by the publisher & author) that are fully viewable in the Google Book Search. Public domain books can also be downloaded as a free PDF file.
--Limited Preview Books are books whose publishers or authors have given Google permission to display a limited number of the books' pages.
This may be the longest blog post I will ever do, but well worth
it. Many thanks go out to my hero Patrick Crispen for compiling
such amazing Google research over the years. If you've enjoyed this
collection of tools, you have him and Google's talented staff to thank.
