This is the first variorum edition of the works of William Stanley Jevons (1835-1882), covering The Coal Question and The Theory of Political Economy, two of the most important books in economics and the social history of Victorian Britain.

Both books were revised by Jevons during his life time and this variorum edition includes meticulously studied textual comparisons, not only between the different editions revised by Jevons himself, but also with the ones posthumously published, such as the 2nd and 3rd editions of The Coal Question, the 2nd to 5th editions The Theory of Political Economy and the edition edited by R. D. Collison Black. The comparisons cover the statistical data and various charts as well as the texts, all of which reveal the flow of ideas of Jevons according to the social changes.

Including a new introduction by the editor, a complete bibliography and name index this collection will be an indispensable research resource for students and scholars of the history of economic thought and of nineteenth-century England.
