I have emailed Logos twice about a Dallas Willard collection. Sure seems like a small group of important books that should be nice to have available for my logos library.
Yup, He died earlier this year, and I proposed a collection of his works in honor of his passing:

It seems that a lot of the great contemporary Christian thinkers/writers are dying without Logos having a substantial collection of their works or in some cases without any of them (also within the past couple of years: John Stott, Robert Farrar Capon -- just the other day) and a bit longer ago (while I was still in seminary), Henri Nouwen and Lesslie Newbigin. And there've been others I'm forgetting at the moment. Fortunately Colin Gunton who also died while I was in seminary did not share their fate, but I'm still waiting for Logos to get his most important work The One, The Three, and the Many: God, Creation, and the Culture of Modernity. OK, I'm rambling off topic. Sorry.
