CAS STNext Database Clusters

STNext database clusters group together similar databases to help you find answers to your search question.

Some clusters contain databases that cover the same subject area, such as agriculture or toxicology. Others contain databases that share a similar feature; for example, the FULLTEXT cluster includes databases that contain the full text of journal articles and patents.

To search all of the databases in a cluster at once, enter FILE or INDEX followed by the cluster name. Then enter your query. To display the list of clusters while online, enter HELP CLUSTER.

The CAS STNext Database Clusters guide (PDF) provides a cross referenced listing of cluster names with associated databases, and database names with clusters they are part of.
