Wealth of comparative and historical material in Hein Online’s Classics.
I just stumbled over a book I never knew existed:
1884 W. T. S. Daniel, The History and Origin of the Law Reports,
Together with a Compilation of Various Documents Shewing the Progress and Result of Proceedings Taken for Their Establishment and the Condition of the Reports on the 31st December, 1883
We have been debating law reporting for longer than we suspected.
