The British Society of the History of Philosophy (BSHP) sponsors a book series, published by Oxford University Press, on New Texts in the History of Philosophy. Its aim is to encourage and facilitate the study of all aspects of the history of philosophy, including the rediscovery of neglected elements and the exploration of new approaches to the subject.
More information is available at the BSHP website: https://bshp.org.uk/publications/new-texts-in-the-history-of-philosophy/
I am particularly, though not exclusively, seeking proposals for translations of texts from the Chinese tradition. Please get in touch with me if you would like to submit a proposal: firstname.lastname@example.org
