Do we have any good sources(lecture notes or books) for learning about $Ihara$ Coefficient?

Is there any relation between $Ihara$ Coefficient and the eigenvalues of graphs?

Thanks for any help.

Following Igor Rivin's suggestion I found the thesis of Matthew Horton (student of Stark and Terras) pretty interesting : 'Ihara zeta functions of irregular graphs'.

That's a nice reference! –  Igor Rivin Dec 31 '11 at 18:01
    
Thanks Igor!<br> Another nice reference I just found again is Audrey Terras' recent book "A stroll through the garden of graph zeta function" with an earlier draft available from wikipedia (en.wikipedia.org/wiki/Audrey_Terras) –  Raymond Manzoni Dec 31 '11 at 18:20
    
Dear Raymond, Thank you very much for your most helpful answers. Wishes –  Shahrooz Dec 31 '11 at 23:47

Yes, the good sources are the articles by H. Stark and A. Terras on zeta functions of graphs.
