Currently, when we look through our library, books tend to listed by alphabetical order (whether by title or author), or type. One additional method that I would like to see added is listing authors by their chronology. I like looking at historical documents, so being able to see who wrote at the same (or nearly the same) time period is helpful.
For example, if I'm reading Richard Baxter, Thomas Aquinas, or Polycarp, it would be good to know who else was writing at that time. Being able to re-organize my books (not by publication date, but by their author's lifespan chronology) at the touch of a button would be very useful in historical research.
