Most of the information that makes some of those books worth reading is only easily accessible on the web in the sense that it's pretty easy to find ebooks of many of those books on the web. Many people learn a lot of their development knowledge from the web (and I certainly do as well), but the majority of the web sources for material beyond basic language reference simply extract the easiest to digest parts of the major texts. This is why so much of what many people know about patterns, algorithms, data structures, and even OOP, TDD, Agile, Scrum, etc. is fragmented or even wrong.
