Have you found a clean PDF copy? Start with Chapter 4 (Combinational Logic Design) to see why this book has earned its legendary status among engineering students.
The text is structured to follow the progression of most university syllabi: Foundations : Binary systems, logic gates, and Boolean algebra. Combinational Logic : Detailed techniques using K-Maps and Tabulation. Sequential Systems
Use free software like Logisim or Proteus to build the circuits described in the book. Seeing the "high" and "low" states change in real-time reinforces the theory.
