Some references on the justification of logic:
Quine's critique of the idea that logic can be derived from the concept of analyticity can be found in his papers "Truth by Convention", "Two Dogmas of Empiricism" and "Carnap and Logical Truth". These can be found in his collections The Ways of Paradox, and From a Logical Point of View.
Putnam argues that we may have reason to accept that logic is empirical in his paper "Is Logic Empirical?" Boston Studies in the Philosophy of Science 5 (1968).
Michael Dummett argues that the justification of deductive reasoning must be found in a theory of meaning, in "The Justification of Deduction" (1974, in his collection of papers Truth and Other Enigmas).
Laurence BonJour defends the view that a priori knowledge of logic stems from rational insight, independently of experience in his book, In Defense of Pure Reason, Cambridge University Press (1998).
Paul Boghossian attempts to restore the concept of analyticity as a source of a priori knowledge in "Knowledge of Logic" In Paul Boghossian and Christopher Peacocke (eds.), New Essays on the A Priori (2000).
