SMARTracker SDI Option Now Supported in Derwent Files
SMARTracker is a powerful and convenient cross-file current awareness option used to monitor the latest bibliographic references for a substance or a class of substances. Previously available only for CAS Registry® and CAplus®, this valuable option is now also available for Derwent Chemistry Resource® (DCR) and the Derwent World Patents Index® (WPINDEX/WPIDS/WPIX).
SMARTracker begins with a substance search in DCR. Both structure and text-based searches (e.g., molecular formula searches) are supported. The user’s SMARTracker SDI then finds bibliographic references relevant to the substances found in the DCR search in WPINDEX, WPIDS or WPIX, per the user’s specifications.
