Graphs & Digraphs, Fourth Edition

This was the one book assigned for a class where I did NOT have to go out and buy a few other books in order to round out the assigned text. Chartrand has written books on graph theory directed at students of many different levels, and this one is advanced -- but the keynote attribute of this book its thoroughness and accuracy. The proofs depend upon appropriate use of accurate definitions, and here the definitions are VERY clear and specific -- therefore in constructing the proofs in the exercises the student really comes to understand the meaning of the definitions and the concepts they describe. At first I thought this book was going to be unapproachable because it does not kill you with friendly banter, but I have come to appreciate its solid approach and trustworthiness not to lead anyone astray mathematically. By the way, graph theory is really fun. Don't pass us the chance to study it!
