Free ChemSpider on the Web

Just found out about this free-to-access data collection on the web, and want to be sure you know about it, too: ChemSpider is a “collection of compound data from across the web, provided for the benefit of the community by the Royal Society of Chemistry (RSC). It aggregates chemical structures and their associated information into a single searchable repository and makes it available to everybody.” Freely.

The collection builds on sources by adding additional properties, related information, and links back to original data sources. It also offers text and structure searching to find compounds of interest, and provides unique services to improve data through curation and annotation, and to integrate it with users’ applications. The ChemSpider SyntheticPages, CS|SP, “extends the model to cover reactions, providing quick publication, peer review and semantic enhancement of repeatable reactions.”

ChemSpider’s mission is to bring together compound data on the web, improve the quality of public chemistry data sources, provide a publishing platform for the addition and preservation of data, make this data accessible and reusable, and to integrate with publications. All in all, a thoroughly worthy enterprise, so I wanted to give it a shout out here.

More as it happens,

Cheryl LaGuardia About Cheryl LaGuardia

Cheryl LaGuardia always wanted to be a librarian, and has been one for more years than she's going to admit. She cracked open her first CPU to install a CD-ROM card in the mid-1980's, pioneered e-resource reviewing for Library Journal in the early 90's (picture calico bonnets and prairie schooners on the web...), won the Louis Shores / Oryx Press Award for Professional Reviewing, and has been working for truth, justice, and better electronic library resources ever since. Reach her at, where she's a Research Librarian at Harvard University.
