These tabs are 'made for' the USCCB edition of the Catechism - unfortunately (and oddly - as other USCCB publications are) not available through Amazon (but which can be found at any Catholic bookstore - brick and mortar or online). They work very well and allow for quick access to the various sections of the Catechism. I give it five stars because the index tabs are of high quality, very simple to apply and a great reference source.
