TRANweb’s milestone

300,000th record entered in Transportation Library’s periodical index


On November 30th, 2006, the Northwestern University Transportation Library indexed its 300,000th record into TRANweb: the Transportation Library Periodical Index.

TRANweb contains bibliographic citations for journal articles, conference proceedings and books received by the library on transportation and law enforcement topics. Coverage extends back through 1979 for trade journals and through 1976 for scholarly journals. In addition, articles issued through the Transportation Center or the Center for Public Safety (formerly The Traffic Institute), published prior to 1979, have also been added to the index.

Roughly 75% of the trade and scholarly journals, conference proceedings, and books indexed are published in the US and, at the present time, all records are from English-language publications. At least 15% of the indexed records include links to full-text articles. TRANweb grows by about 50,000 citations every four years; it reached 200,000 records in 1998 and 250,000 records in 2002.

For the past 20 years, TRANweb has also been a significant contributor to the world’s largest and most comprehensive bibliographic resource on transportation information: the Transportation Research Information Services (TRIS) database. Produced by the National Research Council’s Transportation Research Board (TRB), TRIS contains more than 643,000 records of published and ongoing research, of which more than 117,000, or 18%, were contributed by the Northwestern University Transportation Library.

The TRIS database is available on the Web as TRIS Online through the Bureau of Transportation Statistics' National Transportation.
