Circulation figures for Royal Society journals c1900-2010

This spreadsheet contains our best data on the actual circulation (including sales, but also, where known, non-commercial distribution, e.g. to fellows, and as gifts/exchanges to learned institutions) <br> From 1955 (when the RS set up its own sales/marketing team) until 1989, the circulation figures were published each year in the Society's YearBook (or, Annual Report, 1980-89). Prior to that, circulation information is only rarely available (as far as we have found so far). After 1990, the Society stopped making its sales/circulation figures public (look at the graph in the second tab, and you'll guess why), but they do survive in internal reports. <br> Tab2 focuses on the Philosophical Transactions and the Proceedings: the earliest data are from 1863, but the series is mostly post-1900. This data was the basis for Figure 3 in my 2022 article 'From philanthropy to business' https://doi.org/10.1098/rsnr.2022.0021 <br> Tab3 focuses on the so-called 'other publications': the Year Book, Biographical Memoirs, and Notes &amp; Records (data starts 1955) <br> Tab4 includes a snapshot of circulation c.1935. This is the most detailed pre-1955 information. It comes from a document prepared by RS staff in late 1935, to provide information to printers interested in tendering for the RS printing contract. A copy of 'Sales and Distribution of Royal Society Periodicals' survives in the archive of Cambridge University Press, held at Cambridge UL, Pr578
