Anne McCaffery has written a whole series called The dragones of Pern, it was the first fantasía book i read and fell in amor with dragones from these books, best libros ever.
Dragonology por Ernest pato, drake (I think) is very good, but it is más like an encyklopedia, in the sense that it describes different types and so on. However it is very entertaining and has beautiful illustrations. Temeraire series is also very good, it is set in the time of Napolean wars and dragones exist, so Britain has Royal Air Force of dragons. It is very nicely written, funny at some parts, the universe is well thought out. The series has six libros in total I think.
