Encasement
After a group of books are printed, they are often put in a case. This is a cloth case that is constructed from boards that have a cloth upholstering. Traditional cloth cases are a single line of boards attached together and covered by the cloth; the insides are papered. The pile of books are placed in the middle board, and the left-hand boards wrap the left side and the front of the books, and the right boards wrap the right side and on top of the left side boards. The right side front board has the title tag pasted on the top right-hand side. The rightmost edge has a lip, from which two straps with ivory or bone tallies are connected to. These straps are pulled down the left side, where there are the loops where they are inserted to secure the whole case together.
Modern cases are much like Western ones. They are basically cuboid with an opening in one side where the books slot in. The Chinese have a separate board to wrap the books before inserting into the case.
