J. Martínez de Bujanda's "Index Librorum Prohibitorum, 1600–1966" lists the authors and writings in the successive editions of the "Index", while Miguel Carvalho Abrantes's "Why Did The Inquisition Ban Certain Books?: A Case Study from Portugal" tries to understand why certain books were forbidden based on a Portuguese edition of the "Index Librorum Prohibitorum" from 1581.
