Ancient books collection

The value of an old book is determined by many factors. The first is the version, followed by the paper. As far as the feel is concerned, the lighter the book, the better. Then there is the theme. Among the classical and historical subsets, subset classes are the most popular because of their small print runs and survival. Modern old books are the most valuable books to record major historical events. Generally speaking, the first edition is the first printing. In addition to a long history, it is important that it is made from the original manuscript with little distortion, which can best record the style of the original, so it has high collection value. Second, we should pay attention to the quantity (circulation) of the world. "Rare things are precious" is a major principle of collection. The high price of Song edition books is mainly due to the long history, migration, war, disaster and other reasons, and few books can be handed down completely.
