All of the Society's publications now had a substantial international circulation; in 1973, for example, just 11% of institutional subscriptions were from the United Kingdom; 50% were from the United States. Contributions, however, were still mostly from British authors: 69% of Royal Society authors were from the United Kingdom in 1974. A Publications Policy Committee suggested that more overseas scientists could be encouraged to submit papers if the requirement to have papers communicated by Fellows was dropped. This did not happen until 1990. There was also a suggestion to create a "C" journal for molecular sciences to attract more authors in that area, but the idea never materialized. The conclusion in 1973 was a general appeal to encourage more British scientists (whether Fellows or not) to publish papers with the Society and to pass on the message to their overseas colleagues; by the early 2000s, the proportion of non-UK authors had risen to around a half; and by 2017 it had passed 80%.
