Abstract: We review theory and observations of the final stages of the evolution of open clusters. The distinguishing features of these ghostly objects depend upon the original membership of the cluster, the fraction of primordial binaries, and the initial mass function. Remnants of rich open clusters are difficult to detect and might exist in large numbers. We then examine the limited observational data available in this field, and discuss how to use the results of numerical integrations to plan future surveys and evaluate the quality of the available observational information. Current observational results render it very hard to distinguish between a poor open cluster, an open cluster remnant, or part of an association.
