A revolution is occurring in information exchange among gerontologists worldwide. For research investigators the increasingly easy accessibility of public use datasets promises to facilitate both research training and useful exchange of evidence. A brief history of the development of public use datasets for research in ageing is provided, and datasets of particular interest are described. While the illustrations focus on experience in the United States the implications of these developments for training and communication among gerontologists worldwide are noted.
