Apostolic Letters

1910 New Catholic Dictionary

Broadly speaking, all documents issued by the Holy See. Before Pius X these were divided into bulls and briefs. Now the term is restricted to documents in brief form used for lesser appointments and for erecting and dividing mission territory, designating basilicas, and approving religious congregations.
