Body of Books - Expansion Review - Beyond The Base Game

About Scholars of the South Tigris: Body of Books, from BoardGameGeek:

In Scholars of the South Tigris: Body of Books, the Caliph has called for a greater focus towards the study of medicine. Doctors from near and far bring books and scrolls, wishing to share their latest discoveries. With this recent influx of knowledge and understanding, there seems no better time to start publishing our latest findings across all fields of science. Body of Books introduces a new black Medicine Research Track, black Dice, and the concept of publishing books. The expansion brings in more of a focus towards engine building and creating interesting combinations of retired translators and published works. -description from the designer
