17 judicial notebooks of Peter King, 1st Baron King, Lord Chancellor of England 1725-1733 They are written in cipher and have not yet been decrypted, but the contents runs chronological order from February 3, 1725/6 to November 17 1733. The notebooks appear to contain notes of Lord King of cases that he heard in Chancery and taken in court.

Note about the shorthand the notebooks are written in. Sir John Baker has identified the shorthand system that Lord Chancellor King used - it is explained in his entry for King's abridgment of criminal law in 'Migrations of Manuscripts 2016' (2017) 38 Journal of Legal History 84, no. 2334.

He notes that 'comparison [of the abridgment of criminal law] with the printed sources cited establishes that it is a version of John Rich’s system, published in 1659 as The Pen’s Dexterity, and in numerous subsequent editions under different titles (Maximum in Miminus, and William Addy’s Stenographia of 1695). The same system was used by Sir George Treby CJCP in his autograph reports (MS in the Middle Temple).'
