The decline of Documentary history.

Jonny linked me this article about the decline of documentary evidence which is certainly a concern for historians. However I think its overblown, officials have never openly committed to the record "it was me wot did it" such big discoveries found in public records are generally because what is controversial now was not controversial then or because committing questionable things to the record was necessary. With new and immediate ways of leaking / sharing data, such as twitter which the article mentions, I think we're just getting documentary evidence in different ways.

The challenge for every good historian has always been getting past the lies and official bluster in documents, those in power have consistently changed up and so have historians. Nonetheless it is interesting to read how the world is recorded nowadays.
