This article presents notes that Russell made while reading the works of Gottlob Frege in 1902. These works include Frege’s books as well as the packet of offprints Frege sent at Russell’s request in June of that year. Russell relied on these notes while composing “Appendix A: The Logical and Arithmetical Doctrines of Frege” to add to The Principles of Mathematics, which was then in press. A transcription of the marginal comments in those works of Frege appeared in the previous issue of this journal.
