"There is another rare feature that places his books among the remnants of a type museum -- the setting of a catchword at the bottom of the right-hand page. This is a preview of the first word on the next page, and aid intended to smooth the flow when books are read aloud." from Just My Type (Simon Garfield, 2010) [1]
As you may already know, similar technique was used in Persian and Arabic manuscripts, but for another reason. It was the way to keep account of order the of pages of the book, before page numbers become mainstream. And it was a little different, in the way that there was one (or a couple) of words from previous page on top of the next page as well.
Does anyone here has a copy (scanned, photographed, etc) of such manuscripts to share with the list?
And IIRC there's a name for those words or the method. Anyone remembers or knows a resource to go to?
Thanks,
