The fundamental and distinctive feature of this monograph is its methodological approach, which bases itself on philology. This is the key point that sets the book apart, as previous works on Nôm script have often prioritized the historical linguistics of Vietnamese over the study of philology when exploring the wealth of Nôm script literature. By returning philology to the forefront of Nôm script research, this book, from a cultural history perspective, addresses a key weakness in previous studies: the tendency to focus too heavily on early-dated literature while neglecting later works, particularly those from the 19th and early 20th centuries. Through this research, Professor Nguyễn Quang Hồng was awarded the National Prize for Science and Technology in 2017. In December 2024, the Chinese translation of this book (喃字文字学概论) was officially published and introduced to Chinese readers by Bashu Publishing House.
