Abstract: In a method of searching for data or data-holding resources (2b, 5-10) stored on a distributed system (1), the data stored on the system (1) contains a sequential time indicator relating to the point in time or period when the data is or was available on the system (1). The search terms which define the search conditions comprise a time parameter which confines the search to the point in time and/or period defined by the time parameter. In a method of accessing resources (2b, 5-10) on a distributed system and of receiving and/or displaying data stored on said resources (2b, 5-10), when the data is displayed the information contained in the sequential time indicator is shown at the same time, and access to the data on the system (1) takes place as a function of a presettable time parameter.
