I'm a little confused about the problem here.
From what I understand, writers and/or publishers have the option to A) sit back and collect royalties on all the work Google does with their work or B) be removed from Google's database and thus miss out on the income from it.
Where, exactly, is the issue there? I'm just not seeing it. If they have an issue with Google, they can just say "no thanks" and be in exactly the same position they were before Google even came up with this concept, or they can jump in and earn a few extra bucks without having to do jack squat.
I have to be missing something here. Or are these authors just as idiotic as they seem to be?
There are some who believe that Google making a few pages of their books available online is going to cost them sales.
Google is scanning all pages, but only intends to make a few pages available as a "preview" if you hit them in a search, unless the work is in the public domain. While it might be possible to eventually get an entire book this way, it would be a lot less work to find another way to pirate it (or just, y'know, buy it.) So, those who are concerned they will miss out on sales because of this seem misinformed or overly paranoid.
