Dear Yingmei Liu,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located 19 record series related to Taiwan and Taipei. Some of these records are unclassified, while others may still be classified in whole or in part. For more information about these records, please contact the National Archives at College Park - Textual Reference (RDT2) via email at Archives2reference@nara.gov.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDT2. We apologize for this inconvenience and appreciate your understanding and patience.
As a public health precaution due to COVID-19, all National Archives research rooms nationwide, including those at Presidential Libraries, are closed to the public until further notice. Please check NARA’s web page about COVID-19 updates for the latest information. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Best of luck with your research!
