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. <br> 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 . <br> 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. <br> 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 &amp; Francis) - and the archives of T&amp;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)

本电子表格收录了我们目前已搜集到的、有关《哲学汇刊》（Philosophical Transactions）与《皇家学会会报》（Proceedings of the Royal Society）的印量数据。
《哲学汇刊》创刊于1665年，并于1887年拆分为A辑与B辑，因此本表格包含两个工作表，分别对应拆分前后的《哲学汇刊》相关数据。
《皇家学会会报》创刊于1831年，并于1905年拆分为A辑与B辑，同样设有两个工作表，分别对应拆分前后的《皇家学会会报》相关数据。
本数据集存在大量缺失。1752年皇家学会接手《哲学汇刊》后，按理来说印刷与出版细节的记录应当更为完善，但印量数据极少出现在理事会会议纪要中。
现存最完整的数据来自19世纪期刊由理查德·泰勒（后更名为Taylor & Francis）印刷的时期——Taylor & Francis的档案馆留存有记录印量详情的分类账册。
针对20世纪的相关数据，仅能从零星的报告或评述中获取印量信息；不过可基于1955年后的已知发行量数据估算最低印量，详见单独文件。
