China from Empire to Republic is an ongoing Gale publishing programme aiming to digitise China-related primary source collections from libraries and archives around the world. Two collections have been released in this programme so far: Missionary, Sinology and Literary Periodicals (1817–1949) and the recent Records of the Maritime Customs Service of China (1854–1949). While the dominant topics covered in these two collections are Chinese diplomacy, foreign relations, economy, politics, Christianity, sinology, education, imperialism, and globalisation, we must not overlook another important topic – ‘overseas Chinese’ or the Chinese diaspora.
