Yes, I really counted with my calculator. There are more than 17,000 e-books for us to read online free of cost. Or, you can just and copy and paste in word and save it for leisurely reading.
But these books are not like other ebooks we have come across that are presented in PDF format. These so called ebooks are presented just as words in the web page itself. If we want to store it, we can do only copy and paste.
Of course, you can always save the entire web page itself but that is your choice.
Following the catalog of ebooks. I skimmed through a few and let me tell you that that quality of the content is just superb. A 'must bookmark' web site.
