The reference collections of most research libraries contain a readily identifiable collection of standard paper sourcesused in locating tests and test-related materials for education andpsychology. Yet currently there is no electronic equivalent, no set ofInternet resources that has been identified as constituting an onlineliterature on tests and measurements. This study attempts to investigate what resources are now available on the Internet for tests andmeasurements, and identifies the most useful ones. In order to keepthe study manageable, the emphasis is on resources for psychologcal testing, with some educational psychology materials included as well. Whenever possible, evaluative summaries of these resourceshave been included.
