International Transport Research Documentation has had the ITRD database at its heart - a co-operative worldwide database of published information on transport and transport research.
ITRD contains over 400 000 bibliographical references and around 4 000 are added each year with an increasingly number of links to open-access publications.
Each record contains an informative abstract in one of the four official ITRD languages: English, French, German, and Spanish. The ITRD multilingual thesaurus allows searching by the term code which is the same whatever the language of abstract.
Input to the ITRD database is provided by ITRD members, which represent internationally renowned institutes. ITRD is also a group of transport librarians and a platform for discussion and exchange on transport documentation.
Since January 2011, the ITRD database and the Transportation Research Information Services (TRIS) database of TRB (Washington) are integrated into a new product called TRID - the TRIS and ITRD Database.
