This is the central question for many searchers. The straightforward answer is that there hasn't been a significantly revised or updated "new" edition of The Elements of Grammar published in recent years. The book's primary print run was released under two different imprints: a paperback edition by Collier Books/Macmillan Publishing in 1986 and another by Macmillan in 1996. The 1996 printing is essentially the same text; it is not a revised edition. Therefore, when people search for a "new" version, they are likely seeking a recently printed copy or a digital copy (PDF) for convenience.
