Try google books, with only full view books selected: Here is the link for chess openings on books.google.com: http://books.google.com/books?as_brr=1&q=chess+openings&btnG=Search+Books

The books are old, but in chess...Does that matter?

johndy, I try this and I find many books but all too much older for me.  I need the good ebooks for the chess current timings.  

Anybody have the ebooks to share please?

Try Filestube or Scribd. They're both great online resources for ebooks. Illegal, but great.
