In 2010, as you may know, Tor Books published the first volume of Bill's biography of Robert Heinlein, Robert A. Heinlein: In Dialogue with His Century: Volume 1 (1907-1948): Learning Curve. As I understand it, Bill fought hard for "In Dialogue with His Century," a subtitle he intended to cover both volumes, and Tor acceeded to his wishes.

The second and final volume will emerge on 3 June. Many reviewers have already received "advanced reading copies," and many retailers are geared up to sell the book. So it is mentioned on many places on the Web.
Trouble is, they can't agree on exactly what the title should be, nor how to punctuate it.

(At least none of these aspire to the triply-becoloned status of Amazon's title for Volume 1.)
So how should I refer to this book?* As I said, I wish I could ask the author.
Perhaps if this matter can be sorted out, I too will become The Man Who Learned Better.
*Returning the courtesy, because this book refers to me, just as Volume 1 did. On page 495, I'm cited as a source for a tiny, tiny piece of information about Robert Cornog's security-clearance troubles. Glad I could contribute a small brick to Bill Patterson's cathedral.
