His chief exegetical works are his Philologisch-kritischer and historischer Kommentar fiber das Neue Testament (4 vols., 1800-1804); Philologischer Clavis fiber die Psalmen (1791); and Philologischer Clavis fiber Jesaias (1793); and particularly his Exegetisches Handbuch fiber die drei ersten Evangelien (3 vols., 1830-1833; 2nd ed., 1841-1842).
William Oughtred, a contemporary of Harriot, published an algebra, Clavis mathematicae, simultaneously with Harriot's treatise.
In 1712 he wrote two essays, which are still in manuscript, one on substance and accident, and the other called Clavis Philosophica.
His chief work appeared in 1713, under the title Clavis Universalis, or a New Inquiry after Truth, being a Demonstration of the NonExistence or Impossibility of an External World 1 (printed privately, Edinburgh, 1836, and reprinted in Metaphysical Tracts, 1837, edited by Sam.

- By consulting an account of my expenses at Cambridge, in the years 1663 and 1664, I find that in the year 1664 a little before Christmas, I, being then Senior Sophister, bought Schooten's Miscellanies and Cartes' Geometry (having read this Geometry and Oughtred's Clavis clean over half a year before), and borrowed Wallis's works, and by consequence made these annotations out of Schooten and Wallis, in winter between the years 1664 and 1665.
