Surely there has to be a limit to how much valuable material you want to publish, though, before it starts becoming counter-productive? If so, how do you know what that limit is? Trial and error, I guess? For example, I'm having a discussion with my boss currently about whether all our books should be available to download online as pdfs. He thinks it will decrease sales. I think it will increase them because most people don't like reading off a screen and won't want to print off c.150pgs, but the pdf being there gives them a sight of what the content and quality of the work is like. The compromise would be to go to the half-way house like Amazon do and just allow people to read a bit of it as a 'taster'. Thoughts, Rusty?
