Oops, change:
name = User.find(session[:user_id])

To:
name = User.find(session[:user_id], :select => 'screen_name').screen_name

Or maybe clearer:

def logout
@title = "Login - Books"

user = User.find(session[:user_id], :select => 'screen_name')
session[:user_id] != nil
flash[:notice] = "You have sucessfully been logged out #{user.screen_name}!"
redirect_to :controller => :books, :action => :index
end

And yes, you need the additional end to close the class.
