It is interesting that so many articles are historical essays from deceased authors, such as the essays from Fr. Guardini (d. 1968), Card. Taguchi (d. 1978), Card. Bea (d. 1968), and Fr. Zerafa (d. 2011). Is this typical of this series? For some reason, I had thought it mostly published original contemporary work.
The majority of articles are from contemporary authors, although they reserve a few spots for "classics" that apply to topic at hand.
