Print run data for Royal Society journals 1665-1970

  This spreadsheet contains all the data we have so far managed to   gather on the print runs of the Philosophical Transactions and the   Proceedings of the Royal Society.                      

Philosophical   Transactions was founded in 1665, and split into series A and series B in   1887: there are therefore two tabs, dealing with Transaction before and after   the split .

Proceedings   was founded in 1831, and split into series A and series B in 1905: again,   there are two tabs, dealing with Proceedings before and after the split.                    

The data are very, very incomplete. After the Royal Society took   ownership of the Transactions in 1752, one might have expected better records   of printing/publishing details - but print run rarely appears in the Council   Minutes. The best data come from the period in the 19th century, when the   journals were printed by Richard Taylor (later Taylor & Francis) - and   the archives of T&F include ledgers giving details of the print runs. For   the 20th century, there are only very occasional reports/reviews that mention   print run (though a minimum estimate for print runs can be based upon the   known circulation figures after 1955 - see separate file)
