AMSTERDAM, July 20, 2010 /PRNewswire/ -- Elsevier, a world-leading publisher of scientific, medical and technical products and services, today introduced a new feature on ScienceDirect that improves the discoverability and usefulness of scientific chemistry content. As such, this added functionality enhances the value of the content for both authors and readers in chemistry.

Starting with two Elsevier chemistry journals, authors are invited to submit structure (MOL) files of their key compounds alongside their articles. Elsevier will use these structure files to add compound identifiers - International Chemical Identifier (InChI) keys* - to the article, increasing the discoverability of both the article and its key compounds on ScienceDirect and through search engines. In addition, the structure files are used to visually display all key compounds of the article in a single scrollable list, with additional functionality such as links to Reaxys (https://www.reaxys.com/reaxys/session.do), Elsevier's web-based chemistry database, and Google.

By employing the structure files as submitted by the author, this new feature improves the value of our content above and beyond what can be done automatically through, for instance, text mining. It ensures that the most relevant compounds are identified, visualized, and made available for search and download, said IJsbrand Jan Aalbersberg, Vice President for Content Innovation at Elsevier. He added: Making the MOL files of key compounds available at ScienceDirect (http://www.sciencedirect.com/) and, at the same time, using Reaxys to show the corresponding structures, ties into Elsevier's strategy to enrich the content of ScienceDirect. The use of InChI keys improves discoverability of compounds within the chemistry scientific literature, facilitating and accelerating connectivity to other research tools and content sources. It helps researchers unravel deep layers of information, otherwise hidden in the full text, therewith increasing their research productivity.

The new feature will greatly enhance the utility of ScienceDirect articles and allow readers to easily go beyond the content of an article and to view chemical compounds in a much broader scope. Creating sub-structure searches in Reaxys(R) directly from within an article has never been easier; a simple mouse-click can provide insights that would not have been discovered before.

The linking of data and content has the potential to streamline the research process, bringing to researchers more relevant information with fewer clicks and through quicker searches. With this in mind, ScienceDirect has built the capability to quickly plug in specialized applications as they are developed, so that external data or relevant analysis tools can be integrated directly in the online article as opportunities emerge. More of such integrations are planned for the near future.
