While my use of the word is a publisher- and literary-agent-approved marketing application of "bestseller," I've decided that the marketing puffery isn't worth the hassle. Just as Caesar said of Pompeia at their divorce, "my wife ought not even to be under suspicion" (Plutarch, Caesar, 10.9), I want to make sure no one is confused or upset by my use of marketing words. Therefore, I have amended my biography page to highlight that my Critical Companion to Ancient Aliens achieved Amazon.com bestseller status in the archaeology category in 2012, something that has always been acknowledged in the footnotes. By bringing this to the fore and shifting the adjective "bestselling" from my name to the book's, I hope this will clear up the angry confusion.
I have posted all of this information here to ensure that this change is public and documented so I can't be accused of "secretly" changing anything.
