The standard collection of Berkeley's work is the nine volume The Works of George Berkeley, Bishop of Cloyne edited by Jessup and Luce, and the standard collection of Hume's work is the eight volume Clarendon Hume Edition Series under Beauchamp, Norton, and Stewart as general editors. For the Berkeley, your professor probably has in mind the collection Philosophical Works; Including the Works on Vision edited by Ayers. For the Hume, the Selby-Bigge/Nidditch editions were standard until recently and remain widely used. For the Kant, the standard edition is The Cambridge Edition of the Works of Immanuel Kant series which is under the general editorship of Guyer and Wood but which includes work by other translators as well. And the Pluhar translation of Kant's Critique of Pure Reason, which was the previous standard, remains widely used.
