Digitizing Books-Google has problem's

I think digitizing books is helpful but at the same time I also think its useless to do so. Google is digitizing books not publically but instead for private use! In other words they are going to charge people to read a book online rather than just let you read it for free like at a library. Most of the books that Google’s doing this to; are all under copyright laws which they are completely ignoring and not getting the permission of the authors before they do so. Some of the books however are up for grabs (meaning that they are allowed to do this) because the copyright has run out on them. All in all I think that Google is doing the wrong thing even if they decided to go and find the authors finally and TRY to get their permission.
