When did the project begin and how long until it is finished?

The project began in the 1940s as the brainchild of Julian P. Boyd, Princeton Librarian who served on the national Jefferson Bicentennial Commission. Originally conceived as taking about 42 volumes and at least a decade to complete, the sheer size of the edition grew as more documents came to light. With the first volume published in 1950, the project is currently on a steady pace of producing a volume each year. Based on the experience of other Founding Fathers projects dealing with the presidency, a reasonable estimate of the total number of volumes projected for the edition is 62.
