Abstract
A significant fraction of very metal-poor stars have unexpectedly high carbon abundances. I recap on their discovery, describe the results of high-resolution spectroscopic studies of their composition, and consider possible origins. It is now clear that at least two, and possibly three different explanations are needed for their general characteristics.
