The marginalia hunt has started

Started out with the most recent and surely the most corpulent title of the corpus: Corpvs Ivris Civilis,  Lvgduni 1600 (symptomatic or sympathetic echo's of corpus?), a particularly voluminous set of four volumes on law with printed glosses by Accursius. Systematically leaved through thousands+ pages of text. With the exception of two 20th century library stamps, no ownership marks or marginalia to be found. Pristine pages! Wonder if anyone has ever set eyes on this text and thinking about content versus form. Printed in red and black, decorative initials, head and tailpieces throughout, inserts, different lettertypes for glosses, foot and sidenotes etc., clearly based on the layout of the manuscripts of the middle ages.

The structure is inviting, icons and colours; the content is defeating, considering the absence of marginalia, maybe also for contemporary readers.
Developing a fast way of going through the pages, but don't want to miss even one meaningful trace of use. Checking the first volume went painstakingly slow, by the fourth volume speed picked up.
Two more marginalia-less books leave me somewhat dissapointed, but as all three titles were printed in 1600 and therefore are part of the end of my timeline, their lack of marginalia does not discourage me. The library stamps found in the books could be a reason for their virginity. Libraries do not like to have 'sullied' books in their collections.
Time to start asking for some earlier titles.
