About the OS studbook
Oldenburg's jumping-bred studbook — the registry under which Chacco-Blue stood, focused purely on showjumping performance.
A studbook is the breed registry a horse is recorded and approved with — many top stallions carry approvals from several studbooks at once, so a horse can rightly appear under more than one registry here.
