I just discovered Letters of Note, a surprisingly interesting new website.

Letters of Note is an attempt to gather and sort fascinating letters, postcards, telegrams, faxes, and memos. Scans/photos where possible. Fakes will be sneered at. Updated 2-3 times every weekday.

I Was Ready To Sink Into The Earth With Shame – a 9th Century Chinese form letter for apologising to one’s host for being embarrassingly drunk.

The Masked Letter – written in 1777, and an example of an early code.

The Result Would Be A Catastrophe – a memo from an engineer who raised concerns about the exact issue that led to the Challenger Space Shuttle explosion in 1986.
