The Holy Office granted certain licenses to some people to read forbidden books, academies or convents that required them. Applicants should first check that such reading was necessary for a good performance of their duties. The license was only to have access to prohibited titles that had already been considered prohibited even for those who were licensed to read those books and therefore their reading was completely prohibited.
The convents kept banned books in a separate place, which they called the "Little Hell". If anyone was caught taking books out of the little hell, they would find him guilty and be taken to the authorities of the Inquisition. Invariably, the poor person received the excommunication and a fine of two hundred ducats.
