Links
There are many sites which deal with Aberfan disaster. A Google search will give you a good start. These are the links I have found the most helpful in my research.
The Aberfan Disaster – This is by far the best and most comprehensive. Written by Iain McLean and Martin Johnes of Nuffield College, Oxford, the site points to sources of further information
The BBC has a wealth of information. Simply put Aberfan into their search engine. I was very moved by a memories section which has a large number of links in an adjacent panel.
British Pathe News has a number of newsreel clips about the disaster.
The Wikipedia entry for Aberfan is useful but has many broken links in its sources section.
For a moving collection of images, the I C Rapoport collection is excellent.
The South Wales Police Museum gives an account from the perspective of the police.
