  In addition to her major work on the syllogism, equivalently on the notion of the antilogism, Ladd-Franklin as well wrote some of the entries in the three-volume work of James Mark Baldwin (1861–1934), Dictionary of Philosophy and Psychology, 1901–1905, for example the entries “syllogism,” “symbolic logic,” and “algebra of logic.” In fact she was an associate editor of Baldwin’s Dictionary. She also wrote at least one related paper in the Journal of Philosophy, Psychology, and Scientific Method, later named simply the Journal of Philosophy.
