A couple of months ago I mentioned my chance discovery of the marvellous French website catho.org which contains numerous primary sources for the study of the Catholic French including the Latin text of the 1917 Code of Canon Law and the 1996 edition of Denzinger's Dogma.
The entire site – design and content – seems to have been adopted by the Congregation for the Clergy for their site clerus.org. On their Magisterium page, they offer Denzinger in English. The text is somewhat older. It stops at what is now DS 3904 (2333 in that edition), the ruling that all must believe in the Assumption of the Virgin Mary in Munificentissimus Deus, 1st November 1950 (n.45 in the English translation at the Vatican website). Much better than nothing.
