You know, those publishers already have a lot of titles "tied down" that I would gladly pay for, but they're not bringing them out as e-books. I'm talking about the back catalog titles of many authors. And so my money stays in my pocket. That being the case I fail to see why the publishers are so eager to tie down even MORE titles. They certainly will not make any money from a product they never offer for sale.
So am I missing something here?

Or are publishers just irrational?
