Some of his key writings include:

* Climate and Time in Their Relation to the Physical Condition of the Earth (1875): This is considered his most important work, where he presented his theory of Quaternary glaciations.

* On the Physical Cause of the Submergence and Emergence of Continents (1864): This book discusses Croll's ideas on the connection between glacial periods and changes in sea level.

* The Philosophical Magazine: He published several papers in this journal, including "On the Physical Cause of the Change of Climate During Geological Epochs" (1864).

Croll's work was influential in the development of paleoclimate research and the understanding of Earth's climate history.
