The Agile Austin user group had sixty-seven people attend a great talk given by John Heinz of gistlabs.com entitled "Test Automation: The Big Picture". John started with a slide saying, "Testing is hard, coding is fun." which was a good start to talk about testing automation.
He reiterated some of the Toyota Production System mantras: Eliminate waste, only work on valuable products for your customer; optimize the whole, not the parts; build quality in, don't test for quality.
He also made it a point to say you shouldn't test everything, because testing is expensive. Testing does have a point of diminishing returns.
John recommended Implementing Lean Software Development by Mary Poppendieck and Tom Poppendieck.
John also recommended the Simian project to detect duplicate code.
