The Archives has preserved a collection of correspondences and manuscripts related to the Special Publication in Commemoration of the Fortieth Anniversary of the Institute of History and Philology, edited by Mou-chin Wang in 1968. In the article “Official Date of the Establishment of the IHP” found within, Wang provides an historical overview of the events concerning the IHP since its founding in 1928 and verifies that the establishment of the IHP was on Oct. 22, a date which was then approved by the Institute Council in that year and still recognized today. The style and layout of the fortieth anniversary special publication were adopted for the Chronicle of the Institute of History and Philology, Academia Sinica, 1928–1998, edited and published in 1998. As 2023 has marked the 95th anniversary of the IHP, these works have served as remarkable references, allowing us to reflect on the past and look forward to the future.
