A search on the term 'digital amnesia' reveals a range of interpretations - from simply being forgetful about where some specific content is located; to the consequences of continual technological innovation that renders old formats obsolete & sometimes unreadable; to the syndrome that follows the relentless re-invention & re-branding of organisations such as government agencies that results in broken URLs. A case in point is the short, but significant, 14-year history of Education Network Australia (edna). Not so many years ago it represented the most prominent collaborative response by the Australian education & training sector to the opportunities of the digital revolution (1997-2011). It's all but vanished, apart from the odd published paper documenting its history. Fortunately, the Internet Archive contains remnants (https://archive.org/).
