Abstract
I give an overview of some of the most used measures of entanglement. To make the presentation self-contained, a number of concepts from quantum information theory are first explained. Then the structure of bipartite entanglement is studied qualitatively, before a number of bipartite entanglement measures are described, both for pure and mixed states. Results from the study of multipartite systems and continuous variable systems are briefly discussed.
