Among my recent interlibrary loan items is a hefty volume about the Diocese of Thái Bình in northern Vietnam. There isn’t a scale in my house, but I’d guess that it is four or five pounds like a college chemistry or ecology textbook. Published in conjunction with the eightieth anniversary of the creation of this diocese, this “yearbook” or “commemorative publication” (kỷ yếu) includes over 700 pages of glossy and thick papers and many photos of people and churches. It offers basic information on both past and present of the dioceses as well as individual parishes and missions. The information may be brief, but they add up to some fascinating insights.
