Register Book of the Royal Society: copies The register book contains copies of scientific papers submitted to the Society - the original documents may be found in the Classified Papers series. The papers were transcribed to establish their precedence for a particular discovery or idea. It follows that not all communications to the Society were registered in this manner, but only those judged to contain some significant original material. The register books are by nature copies of notable documents transcribed into a register, in turn the registers exist in original and copy form as the original register book (RBO) was transcribed in the eighteenth century to form this copy. 1661-1738
