Suggest books on Combinatorial Graph Theory I am going to start self-studying Combinatorial Graph Theory. Kindly suggest books or study materials available online. 
I have been told that it is basically application of linear algebra, mainly the eigenvalue/eigenvector things on Graph Theory. So, any book or material focusing on that particular aspect broadly will be very helpful. 
Till date I have studied only linear algebra and little to no introductory graph theory and I have zero knowledge of combinatorics (in case that is also required). So, kindly suggest something that can be handled by a beginner like me.
Thank  you very much.

Combinatorics and Graph Theory by Harris, Hirst and Mossinghoff covers a wide variety of topics in combinatorics and graph theory. It includes results and problems that cross subdisciplines, emphasizing relationships between different areas of mathematics.
