The Master of the Rolls - Who, What, Why, Which Rolls?

Today I learnt which rolls the Master of the Rolls is master of.

The Master of the Rolls (currently Lord Neuberger of Abbotsbury) is the Head of Civil Justice, the most senior judge dealing with the civil work of the Court of Appeal in England and Wales. As President of the Civil Division of the CoA, he is also responsible for the organisation of the work of the other judges,* is in charge of documents of national importance, and also appoints members of the Solicitor's Disciplinary Tribunal.**

Geoffrey Rivlin gives an interesting account of the history of the office of Master of the Roles in his wonderful book Understanding the Law (5th ed, 2009, OUP). Rivlin explains that there was originally a Clerk or Curator of the Rolls who was "responsible for the safe-keeping of all charters, patents, and records of the most important judgments and decisions of the courts which were entered upon the Parchment Rolls". The role gradually developed, and he became the chief clerk (Master) who advised the Lord Chancellor in the Court of Chancery, and then the deputy judge in that court. "His combined duties as clerk and judge (Master) and keeper of records (Rolls) led to the title Master of the Rolls."**
