Tasks that take place over a long period of time or collaborative tasks where participants are required to develop an understanding of each other's effort benefit from better communication about activities. We are exploring facilities for linking directly to activity in hypertext rather than to documents describing activity. One way of preserving a record of activity is to store and access document history. Based on the existing use of edit history in the Visual Knowledge Builder (VKB), this paper explores functionality surrounding activity links, links whose destination anchors are a span of activity within the edit history. We describe enhancements in VKB that support reviewing activities in the hypertext space and authoring activity links. Copyright 2005 ACM.
