 Boring 1950 has an excellent annotated bibliography (344, ff.). Wundt’s entire oeuvre was compiled by his daughter, Eleonore Wundt (1927; cf. esp. Wong 2009: 230–3). An excellent select bibliography organized by theme has been compiled by S. Araujo for Oxford Bibliographies (subscription required). It includes volumes on Wundt’s correspondence, his estate, international library collections and archives, and his global influence.
