Good books on graph theory for self-study? Recently I plan to study graph theory. I tried to read the book A Course in Combinatorics, yet I found the text hard to follow and problems too difficult. I'm just midway in chapter 2 and I already found several problems that I can't solve even after reading the hint and thinking for hours. (Is it just me or is it that the problems in this book are indeed really hard? And should I pursue reading this book?) So I want another book that (hopefully) satisfies the following:


*

*Comprehensive.

*Has good problems with detailed hints (compared to the book above).
