The Index Translationum was created in 1932.
The database contains accumulated bibliographical information on books translated and published in about one hundred of the UNESCO Member States since 1979 and totals more than 2,000,000 entries in all disciplines: literature, social and human sciences, natural and exact sciences, art, history and so on.
Each year, the bibliography centres or national libraries in the participating countries send the UNESCO Secretariat bibliographical data on translated books.
