The Year Book volume is a product of an intense collaborative effort to present the reader with the highest quality text. This year we say a fond farewell to two longterm authors: Larry Grossman and Ethan Felson. Larry wrote the article on “Jewish Communal Affairs” from 1988 to 2015 and served as editor of the Year Book from 2000 to 2008. He provided us with excellent guidance in proceeding through the transition from the previous editorships, under the auspices of the American Jewish Committee, to the new international publisher, Springer. Ethan wrote the article on “National Affairs” from 2006 to 2015 (and was joined by Mark Silk in 2015) while he served in various capacities as vice president and general counsel at the Jewish Council for Public Affairs. More than that, he served as a personal guide, navigating us through the thicket of political issues. To both of these individuals, we all owe a debt of gratitude for their selfless service to producing the Year Book. Of course, our gratitude is extended to a successor author: Mitchell Bard took on Ethan Felson’s (and Mark Silk’s) “National Affairs” article, now focused on the “International Arena.”
