Chemspider: Chemical Search Engine

I have found about this product through the Nature issue dated 8/05/08.
This New Chemical Search Engine can be accessed @ http://www.chemspider.com/
According to their web page:
ChemSpider is a free access service providing a structure centric community for chemists. Providing access to millions of chemical structures and integration to a multitude of other online services ChemSpider is the richest single source of structure-based chemistry information.
It has been built with the intention of aggregating and indexing chemical structures and their associated information into a single searchable repository and make it available to everybody, at no charge.
ChemSpider is a value-added offering of publicly available chemical structures since many additional properties have been added to each of the chemical structures. We intend ChemSpider to offer the fastest chemical structure searches available online and delivered with the flexibility and usability necessary to encourage repeat usage. A quick browse of the manual will help understand how ChemSpider can be of value.

With ChemSpider the intention is to aggregate into a single database all chemical structures available within open access and commercial databases and to provide the necessary pointers from the ChemSpider search engine to the information of interest. This service will allow users to either access the data immediately via open access links or have the information necessary to continue their searches into commercially available systems.
ChemSpider was released in March of 2007. At present the database contains information from such diverse sources as a marine natural products database, from all commercially available ACD/Labs databases, from the EPA’s DSSTox efforts and from a series of chemical vendors. The data collections will continue to expand.
