The UNESCO Index Translationum is an international bibliography of translations which was created in 1932.

The database contains cumulative bibliographical information on books translated and published in about one hundred of the UNESCO Member States since 1979 and totalling more than 1.700,000 entries in all disciplines: literature, social and human sciences, natural and exact sciences, art, history and so forth.  

International cooperation makes the "Index Translationum" a work tool that is unique in the world.

Each year, the bibliography centres or national libraries in the participating countries send to the UNESCO Secretariat the bibliographical data concerning translated books in all fields of knowledge. The references registered before 1979 can be found in the printed editions of the Index Translationum, available in all National depository libraries and at the UNESCO library in Paris.
