Abstract: In China great success has already been achieved in sorting out ancient literary books, which is closely related to the work of collation. The principles and norms, shaped during past long-term practice, of the discipline of collation should be inherited and carried forward. According to different books and demands, approaches to collation might as well differ, and forms to record collation might differ too. All kinds of arbitrariness in collation of ancient literary books, however, should be turnd down.
