So I was in the library one day when I noticed two big, old calculus textbooks sitting on the shelf. One was called Calculus and Analytic Geometry by James E. Shockley. The other was called Calculus by Harley Flanders. Since I didn't have time to look through them, I checked them both out to look at later. Unfortunately, Amazon failed to help me this time since no one had written any reviews on them, so I started reading them on my own. So far, I've enjoyed the rigor of Shockley's book and the feel of Flanders' book. However, I'm still not sure how these books compare with other modern ones. So if anyone here just so happens to have heard of them, what is your opinion of them?
