Part of the challenge of designing systems to support knowledge work is to do so in a
way which is sympathetic to users' uncertainty. NewsHarvester is a test-bed system
designed to support news research and writing in a way that accommodates
uncertainty in relation to information gathering. It does this using `drag-and-link'; a
simple feature by which text extracts copied from source locations are appended with
hyperlinks to force the re-display of the source. We describe the rationale for using
drag-and-link within NewHarvester based on a previous ethnographic study of
journalists, describe its implementation within NewsHarvester, and report a user-
evaluation which compared drag-and-link with printing and standard drag-and-drop
as information gathering mechanisms.
