We had reported in a recent posting about the publication of Bill Baxter and his long time collaborator Laurent Sagart’s book on Old Chinese. Bill and Laurent have just made available nearly 5000 reconstructions of Old Chinese words on the companion website of their book. This adds significantly to the already impressive 1400 reconstructions included in the book. Both the book and the supplementary materials that Bill and Laurent are making available are bound to become indispensable for any scholar of Old Chinese, as well as for researchers interested in language change more generally.
