During the Middle Ages prohibitions of books were far more numerous than in ancient times. Their history is chiefly connected with the names of medieval heretics like Berengarius of Tours, Abelard, John Wyclif, and John Hus. However, especially in the thirteenth and fourteen century, there were also issued prohibitions against various kinds of superstition writings, among them the Talmud and other Jewish books. In this period also, the first decrees about the reading of various translations of the Bible were called forth by the abuses of the Waldenses and Albigensians. What these decrees (e.g., of the synod of Toulouse in 1129, Tarragona in 1234, Oxford in 1408) aimed at was the restriction of Bible-reading in the vernacular.

Let me help you with the next sentence of your carefully sculpted post from the Catholic Encyclopedia:
“A general prohibition was never in existence.”
