It’s no surprise that there are books everywhere. This is a university, after all. Books are one of the biggest threads connecting every department and avenue of study.
Sometimes it’s fun to flip open some of the old tomes gathering dust on mostly-forgotten shelves. This was, presumably, a useful reference when acquired in 1973 or so. Flipping open the front cover, it’s not hard to imagine that someone got at least $5 worth of use out of this.
That said, this is not the most compelling cover-to-cover read, unless you’re really into data tables for the sake of data tables. Front to back, it’s tables of lunar positions and times over a span of 2,652 years. From what seems like an arbitrary start – 1,001 is a pretty fine number – to around the death of Johannes Kepler (November 1630) makes for a lot of potential eclipses and other lunar phenomena that would get the attention of ancient writers.
Folks around here are already talking seriously about the solar eclipse in April of 2024. Syzygies are a big deal.
Syzygy. Y-Y-Y. Great word.
