even though the cookbook yields coefficients for Direct 1 or Direct 2

I've often wondered about the relationship between the z-plane transfer
function and state variable form. Can anyone recommend a good reference
(book?) that clarifies the relationship between direct form and state
variable form in digital filters?
Thank you
