Handwritten manuscripts of an author, whether they are complete literary/academic works or developing/scattered writings (such as correspondence, diaries, archival texts, and formal documents), can be treated as a subject of studies. The unpublished texts that only exists in the form of manuscript after an author's passing are, without a doubt, most valuable, but even the manuscripts of published materials, if available, deserve our attention. With the advancement of technology, more and more manuscripts reproduced and published, so that researchers can have easy access to them at their own time and place, without having to organize lengthy stays at a museum or archive. Integrating manuscript studies-including the screening, emendation, and analysis of manuscripts-into foundational training for literary historians has, thus, become viable. The present paper is approaching this issue from four main perspectives, namely "political legacy and calligraphy," "auction price and reputation rights," "academic value of manuscripts," and the "authentication and studies of manuscripts."
