This theme issue of the Journal of American-East Asian Relations is different. It presents three articles describing primary source and archival materials related to World War ii in the British Commonwealth, China, and Japan with which readers might not be immediately familiar. These essays are timely and have special value because covid-19 led to the closing of archives and manuscript repositories across the globe. However, a positive outcome of the pandemic has been that it has accelerated digitization of primary sources and electronic access to them. Peter Mauch, senior lecturer in Asian History at Western Sydney University, deserves praise for proposing this theme issue and, as guest editor, bringing it to fruition. Authors Priscilla Roberts of the City University of Macau, Aaron William Moore of the University of Edinburgh, and Kazufumi Hamai of Teikyo University and Mauch have written detailed and discerning surveys of the primary sources available on East Asia during World War ii. Readers will be pleased to learn that the next installment of the journal also will be a theme issue on the topic of “Southeast Asia after Vietnam: Persistence and Transformation.” Mark Atwood Lawrence of the University of Texas and Jana K. Lipton of Tulane University will serve as guest editors and Mattias E. Fibiger of the Harvard Business School, Wen-Qing Ngoei of the Singapore Management University, and Joy Sales of California State University, Los Angeles will contribute the articles. The editor-in-chief welcomes the receipt of proposals for future theme issues.
