I've heard there are lengthy editorial notes in your edition. Is this still true?

Julian P. Boyd, editor of Volumes 1-20 of The Papers of Thomas Jefferson, intended that the early volumes would contain a greater degree of annotation  than the later ones. Indeed, the extended historical essay was one of Boyd’s contributions to modern editorial design. He also introduced “file folder” treatment of a topic that included an editorial essay accompanying a grouping of related documents printed together. Many of his editorial notes are works of scholarship in and of themselves and could have appeared as separate scholarly articles. Nonetheless, Boyd’s lengthy editorial notes, especially in his later volumes, became targets for criticism about the slowed pace of progress on the edition and the decreased amount of space that could be dedicated to inclusion of transcribed documents. The editorial practice of lengthy notes was subsequently abandoned for the edition  in 1986 (see Vol. 22: vii) and the completed volumes have appeared more rapidly in print ever since as current editors continue to provide what is minimal and essential for understanding the context of a document.
