Dear madam or sir,

Today, CWTS Leiden University launches the Leiden Ranking 2013. The
ranking measures the scientific performance of 500 major universities
worldwide, using a sophisticated set of bibliometric indicators. It is
presented via an intuitive and user-friendly website interface:
www.leidenranking.com. CWTS takes great care in providing accurate
ranking by thoroughly cleaning address data, unifying institute names
and ensuring the completeness of the scientific output.

The Leiden Ranking 2013 feature highlights

Source normalization is a new CWTS-developed approach that has the
advantage of being independent of classification systems that organize
publications or journals into fields. This approach corrects for field
differences by analyzing referencing behaviour at the level of
individual publications.

This new version of the ranking offers the option to compare
scientific performance among universities over 5 broad scientific
disciplines in the following dimensions: impact, output and
collaboration.

Sincerely,

Mark Neijssel M.Sc.
