A System of Logic, Ratiocinative and Inductive, was published in London in 1843 in two volumes and went through eight editions in John Stuart Mill's lifetime, the last revised in 1872. Of its six books, the third, Of Induction, is the longest and the most influential; the library text gives that book alone, from an 1882 American printing of the eighth edition.

Considerations on Representative Government, published in London in 1861, is John Stuart Mill's full treatment of how a free people should be governed.

The Subjection of Women is John Stuart Mill's extended argument that the legal subordination of women to men in mid-Victorian Britain was wrong in principle and an obstacle to human improvement, and that it should give way to perfect equality before the law. Mill drafted it in 1860–1861, after the death of his wife Harriet Taylor Mill, and published it with Longmans in 1869.
