Having the sum total of human knowledge at your fingertips is great.

When I was a kid, we had to pore through the limited resources of the school and public libraries, and any books and magazines owned by people who would let us borrow them.

Now, most widely read material is referenced on the Internet, and answers are just seconds away.

As wonderful as that is, the full text of millions of books is absent from the Internet, being protected by copyright, or material that was never scanned into a computer.

Recently, a federal judge shut down a Google plan to digitize and make millions of books searchable online, but as seen in this  MercuryNews.com article, a new plan could still rise from the ashes, perhaps making a compendious virtual library out of every internet connection worldwide.
