[Blog Post] Analysis of cover attachment and VMS binding.

[ReneZ]

a lot is known about the binding / the cover (terminology is an issue here and I am not the expert).

OK, in another (unrelated) context, I had the fortune to learn more about the correct terminology.
As a consequence, I will need to update the web page that Wladimir was referring to in the opening post.
In summary:

The term "binding" refers to the boards and spine and covering material of a book—a full leather binding, or a limp parchment binding, etc. A binding is the protective covering.

When referring to the way the quires are attached to each other, it’s referred to as the "sewing structure". There are sewing supports (the cords or thongs the sewing goes around) and there is the sewing itself, which is the thread that goes through each section/quire and wraps around the supports.
