‎First edition of a main textbook in modern symbolic logic and having an interesting provenance as the copy has belonged to the Danish logician Jørgen Jørgensen.""Modern interest in modal Logic begins with the work of C.I. Lewis, first published in book form in his 'Survey of Symbolic Logic' of 1918. This theory is commonly called the logic of strict implication, because it was originally put forward in opposition to an account of implication which Lewis thought mistaken.""(Kneale and Kneale ""The Development of Logic"" 1962, p. 548 ff.).‎
