On the opposite side of a page or leaf, often used in books or documents to refer to information that can be found on the back side.
The details of the project can be found overleaf.
Overleaf → It is formed from "over" (meaning above or on top of) and "leaf" (from Old English "leaf", meaning a page or sheet of paper). The word "overleaf" refers to the side of a page that is on the opposite side of the one currently being viewed, or simply the page above.
Think of something that is 'above' ('over') on a 'page' ('leaf') — that's why overleaf means the other side of the page.
