Graph Theory with Applications
J.A. Bondy and U.S.R. Murty

Data Structures and Algorithms
with Object-Oriented Design Patterns in Ruby

I maintain both a Java version and a C++ version. This material is distributed free for educational use. Posting the textbook online is merely the first step toward a much broader vision of a truly interactive eTextbook. See our OpenDSA Project homepage for more details. See here for a brief discussion of how this online textbook and the OpenDSA project came to be.
