The rise of citizen journalist offers alternative views to officially recorded history in every tweet, blog and post. Why is it so important for libraries to preserve Facebook, Twitter and other online conversations? How would our world today be understood 100 years from now if these millions of diverse voices from around the world were lost?

Author John Birmingham talks about why preserving this digital content is vital.

Author and journalist John Birmingham’s books include He Died With a Falafel In His Hand and Leviathan: an unauthorised biography of Sydney, for which he won the National Award for Non-fiction. His most recent fiction series is the Dave Hooper trilogy.
