Don -- This is great. So glad to have found you here via Tim Page on Facebook.

@JJPryor, editor of the Medium publication @Feedium is compiling a list of books Mediumites, that he will publish soon. Not sure what his timetable is, so I threw together something on "Zika: The Emerging Pandemic" here (which you could add to if inclined) so the won't miss the deadline: https://medium.com/feedium/feedium-13-i-want-to-do-you-a-small-favor-for-the-holidays-dda02b1b3846
