I'm not sure of the value for me to catalog all books just for the titles. What I would like is whenever I search Google, it would also search my books and tell me which book to open.

Not sure if that exists, but obviously the hard part is getting access to full-text contents of books - scanning pages by myself would be extremely time consuming.
