Elsevier has added another 600 titles to their abstract and citation database, Scopus. They say that Scopus already covers 15,000 journals so this addition must put them at 15,6000 or thereabouts; certainly a hefty figure however you count it. In contrast, Web of Science presently treats only about 8,700 journals; that being said, the two aren't quite the same thing and they have different guidelines for inclusion but I the differences are blurring and likely don't mean much to many users.
The list of newly added journals can be found at http://www.info.scopus.com/detail/what/documents/titles2008.xls. It's a mixed bag of titles, from many subjects and publishers.
