Radia Perlman's Interconnections 2nd Edition has all the frame formats you could hope for, it covers all the major protocols and lays out byte by byte maps for the frame for each routing protocol. I use this book as the textbook for a Digital Communications class for the local community college, it is in-depth and I believe is close to the top on the recommended reading list for the CCIE anyway. All in all a good investment, although my students claim that most of it is way over their heads. ;-)
Good Luck,
Joe
