Crossfire Gmelin Coverage Enriched With New Data from 1990 to 2000

Over half a million compounds updated or added to the world's largest collection of materials and physical data

FRANKFURT, Germany — August 24, 2006 — MDL Information Systems GmbH and Gesellschaft Deutscher Chemiker e.V. (GDCh, German Chemical Society) are pleased to announce that chemical data spanning the period from 1990 to 2000 has been added to CrossFire Gmelin, the world’s largest compilation of inorganic and organometallic compounds and related physical properties. Information drawn from previously unexcerpted key journals published during this time period, critical to research in material sciences, inorganic or organometallic chemistry and related areas, has been added over the past year and a half. This large block of new compounds, reactions and data, which increases the references/citations by over 10%, will be released this summer with the next update of the database.

“We have been waiting for this data, and our users will be pleased with such an enhancement to Gmelin, one of our important sources,” said Dr. Engelbert Zass of ETH Zurich. “Compared to the number of publications in Gmelin from the period 1990-2000 in, for example, the 2002 version of the database, this is a very significant addition indeed.”

“MDL Information Systems GmbH listened to customers and gave them what they wanted – data from the period 1990 to 2000,” said Prof. Dr. Wolfram Koch, executive director of GDCh, which owns the Gmelin database. “Our ongoing and very successful collaboration with MDL Information Systems GmbH to update CrossFire Gmelin has created the most comprehensive collection of high quality inorganic and organometallic data in the market. Using the Gmelin database, scientists can dramatically reduce the time and cost involved in researching and developing new materials that offer optimum physical properties with minimum development costs.”

With over 100 million experimental facts covering over 2.2 million substances, over 1.7 million reactions and over 1.1 million citations, CrossFire Gmelin is an ideal tool for researchers engaged in designing new materials and catalysts. It covers literature from 1772 to the present. MDL Information Systems GmbH maintains the Gmelin database in partnership with the GDCh, the largest learned society covering the chemical and molecular sciences in continental Europe.
