# List of Catholic titular sees

This is the official list of titular sees of the Catholic Church included in the Annuario Pontificio. Archiepiscopal sees are shown in bold.
The Italian-language Annuario Pontificio devotes some 200 pages to listing these sees, with up to a dozen names on each page. It gives their names in Latin (which are generally the names used also in English) as well as in Italian, and indicates the ancient Roman province to which most of them belonged or other geographical particulars, their status as metropolitan see or suffragan see (of episcopal or archiepiscopal rank), and basic biographical information about their current bishops.
