Suggestions for Graduate-Level Combinatorics/Graph Theory Texts

[ehrenfest]

I have taken an undergraduate course in combinatorics (and graph theory). I am looking for a graduate-level text at that does everything completely rigorouslym and is suitable for self-study. Any suggestions?

Enumerative Combinatorics (vol. 1 & 2) by Richard Stanely

But, its not for the faint of heart.

Maybe van lint's and wilson's book will suit you better, well it depends on the material covered in the course.
