You can use citation searching in SciSearch in two ways:
Search for any documents that have cited one or more references. Use SELECT CIT for several references, or TRANSFER CIT for many references from multiple databases.
Search for “related” documents, i.e., documents that have cited one or more references from the same set of cited references. Related record searching allows you to find documents related to another document or a set of documents by virtue of having cited one or more of the same references.
