Introduction
The National Palace Museum (NPM) houses a great collection of rare books and historical documents, which can be divided into two major categories comprising Rare Books and Historical Documents and Qing Dynasty archives. These precious artifacts culminated in the making of the Rare Books and Secret Archives Treasures from the Collections of the National Palace Museum Special Exhibition by the NPM Department of Rare Books and Historical Documents. To facilitate easy carriage, the Rare Books and Secret Archives Treasures from the Collections of the National Palace Museum was made into a letter-sized book. The outer margin of the book in the front is specially designed for readers and can be used as a bookmark, and the outer margin in the back can be used as an exhibition admission ticket holder, allowing the visitors to keep the admission ticket for memory. These unique designs reveal the efforts made by the editing team, and will surely fascinate the readers.
