I have done similar jobs.  Including scanning ocring and proofreading of large technical manuals.  I know it isn't simple, but it's not brain surgery.  It could also be done independently by several individuals at the same time to make sure they found the same mistakes.  Books are a good value, but my relative pay has been decreasing for years.  Although the value of the written word is priceless, the value of books is relative.  I have read many of your books and listened to them on my mp3 player.  I have checked them out from the library or downloaded them from netlibrary.  Starbucks does use college students to make a cup of coffee.  I won't pay $4 for a cup of coffee, but I know some people will.  Starbuck's does add value.  The convenience, the environment, the whole experience is not something you get when you order a coffee from McDonald's.  Books need to start adding value.  Just doing the same thing on an electronic device doesn't change the experience very much.  In fact I think the whole point of eink was to make the electronic version as close to paper as possible.  To get the same item on a device that is much easier for the publisher to distribute, makes it seem like it should cost less unless some value is added.  So far value is being removed.  You can't touch, smell, feel ebooks.  You can't give them to your child when they go off to college.  You can't get a signed first edition as a gift for a friend.  You can't see that spot where you spilled McDonald's coffee on page 143 when you were laughing  (not a library book).  These are just my opinions.  I know many people will disagree with me, but sometimes I just want a cheap cup of coffee.
