I was studying this book and it surprised me that the bottom right of every page includes the first syllable (?) of the next page's first word. An example below (Leges, Quif):
Following my curiosity, I searched other Latin books and found the same pattern in many of them (e.g here, here, here, or here) but not all (e.g. here, here, or here).
My questions:
- Does this printing style have a name?
- How widespread could we say it was? (perhaps a time-period?)
- What was its function?
