|Question||How can I access the complete, latest version of the UDC scheme?|
The authorised, standard version of the UDC, known as the "UDC Master Reference File", is distributed in English. This file is updated once a year and can be obtained from the UDC Consortium under a MRF user licence. UDC schedules in other languages such as Spanish, French, Russian etc. are published by licensed publishers in their respective countries.
