A collection of 347 songs and poems created, recited, and recorded by Korean women from 1794 to the 1960s. Those works were produced in diverse formats including individual single-leaf documents, scrolls, and a codex. The Naebang-gasa are a record of the views of sequestered women in a male-dominated society of East Asia, serving as a witness of the efforts of women to fight for equality.
This collection also has significance in the evolution of the Korean national script, as an early manifestation of literature in Hangul script, whereas previous Korean literature and items of significance were all written in Chinese script, and almost exclusively by men. Naebang-gasa are included in the Women in History: HERstory exhibition developed by UNESCO Bangkok and MOWCAP, where they are described as important for understanding the transition of Korea into a modern society.
