While some official periodicals may have published more frequently, there was still a long delay from a paper’s submission for review to its actual publication. Smaller periodicals, such as Transactions of the American Philosophical Society, were only published when enough content was available to complete a volume.[28] At the Paris Academy, there was an average delay of three years for publication. At one point the period extended to seven years.[29] The Paris Academy processed submitted articles through the Comité de Librarie, which had the final word on what would or would not be published.[30] In 1703, the mathematician Antoine Parent began a periodical, Researches in Physics and Mathematics, specifically to publish papers that had been rejected by the Comité.[28]
