Use of Google Books and Google Scholar

I frequently use Google Books and Google Scholar for my work and studies. I have found them to be a great resource, almost like having a library with you.
The books and articles you find can vary in their availability. They can be give you a preview or even a full view of the book. There are loads of topics and you can even create your own 'library' to find the books you want quickly. You can save them under 'reviewed', 'favorites', 'reading now', 'to read' and 'read'.

I, who still beleive in the old-fashioned book as being essential, found this site to be the best of both worlds - where students can still be digitial whilst at the same time reading a book.

I feel this is one of the greatest initiatives on the web.
