Borgesian Weekend

I have a copy of the Shorter Oxford English Dictionary. I received my copy shrink-wrapped, new, and unopened. While looking up an archaic d-word yesterday, the pages of Vol. I fell open, and not to one of the places marked by the OED’s fine blue ribbon bookmarks. No, a slip of paper had done the job — a slim, rectangular slip of paper torn off at one end. And on this piece of paper is a written message. In Chinese Japanese.

Help me decipher the text! I promise not to shoot you when I learn the secret.
