Jean Denis de Sallo, Journal des sçavans ... . Amsterdam: P. Le Grand (etc.), 1665 [i.e. 1684]- . [Reprint ed.]
The Journal is generally recognized as the first published scientific journal, although early issues might be described more properly as an eclectic gazetteer of general notes and observations, both scientific and otherwise. Previously, scientific scholarly communication had been not through journals but by private correspondence. Begun by Denys de Sallo in Paris on January 5, 1665, the work was suppressed on March 30 after 13 issues appeared. Publication resumed the following January. From 1675-1709, a number was published weekly or bi-weekly, more or less, before becoming a monthly in 1710. In 1684, due both to the increasing popularity of the work and the difficulty in obtaining copies, the Dutch printer published a reprint edition of all previous issues, and he continued with reprints of the Paris issues as those copies arrived in Amsterdam, often with added non-Parisian content.
