Thank you for posting this. I just saw the first part of it because I don't have time right now, but it looks interesting. I moved it, as the Admin, because we have a section for videos just like this.
If anyone is wondering, I clicked on it because it said YouTube, but here's a description if you're a bit leary (I usually am).
Published on Mar 8, 2015 Many historical documents from the 17th to the 19th centuries remain unread in archives because they were written in shorthand. This talk describes a case study deciphering such documents. The shorthand is from the 74 notebooks of Justice John Hyde, sitting on the first Supreme Court in British India in Calcutta, where the notebooks (1774-1796) still reside. In and among the plain English notes there are shorthand entries varying from one sentence to three pages. Hyde used shorthand to hide his secret thoughts that were taboo in his time and place. The notebooks themselves are difficult to access (very) and the deciphered content is new historical data.
