The juan 卷 "scroll" is a counting unit used in traditional Chinese books. It is often congruent to one chapter, but not necessarily. One juan may correspond to one chapter but may also contain several chapters. Very long chapters can also stretch over several "scrolls".
In antiquity, the writing material for all kinds of records, from books to tax registers (to the right see a fragment of an accountancy scroll from the Han period found in Juyan 居延, Gansu), were bamboo slips (jian 簡) that were inscribed vertically from right to left with one column per slip, and tied together with two to three threads. The length of such writing "boards" was less than one metre. They were rolled up and stored in shelves in the libraries and archives as scrolls. Coherent books thus consisted of several scrolls that often included one chapter or several smaller chapters. The name of the book and of the chapter were written either on the back of the scroll, visible from outside, or on the first slip.
With the invention of paper during the Han period 漢 (206 BCE-220 CE), a much lighter and more comfortable, yet more perishable, writing material was at hand. Bamboo slips were not totally given up, and therefore the counting unit "scroll" still played a role. It was even used when bamboo was not longer used as writing material because the successor material paper was tied together by different ways to small booklets that likewise had approximately the same size to each other, like the bamboo scrolls before. A booklet now contained several scrolls. The roughly fixed size of scrolls was a good measure to indicate the size of a book (the more accurate is to give the number of characters). Furthermore, scrolls were numbered and thus served as a chapter numbering. Today, the word juan therefore means "chapter".
