I can recommend lists of resources compiled by these respected testers whose opinions I share:

• James Bach (Software Testing resources)
• Michael Bolton (Software Testing resources)
  
• Alex Podelko (Performance Testing etc. resources)
  (Why should I use the Ctrl-C / Ctrl-V method to create my own list?)

In addition I can recommend:

• The Structure of Scientific Revolutions by Thomas S. Kuhn
  Thomas Kuhn has discovered that modern science is a social phenomenon - it can't be understood without paying attention to schools of science or groups of scientists.
  Have you ever wondered about the long coexistense of the Waterfall / CMM paradigms and the Rapid and Agile movement, which are almost completely irreconcilable? You will find the answer to this puzzle in Thomas Khun's book.
