You might have to play a bit of hide and seek if you visit this textbook and have a number of browser windows open. The warning page came up fine for me but the pop-up that contained the text was behind a bunch of junk I had going on my machine.

That said, I think this introduction to logic textbook is worth looking for. It was written by J. David Velleman, Professor of Philosophy at New York University. The reason behind the pop-up is that this is an interactive textbook. Velleman designed the text to be an interactive learning tool and as such, it has fewer examples and less repetition. He suggests that if you do not take the time to interact with the illustrations you won’t understand the text. Most sections of the text also include interactive exercises.
