Anotations

Scope note:

Uncommon book format consisting of 64 pages or 32 leaves. Although it may be formed by making 5 right angles from the original sheet, the process is hampered by trapped air and buckling. Instead, the book format is created by folding an entire sheet with parallel folds, and folding a half sheet with two parallel and two right angle folds, and inserting the folded half sheet into the former.
