US Patent 8489587 Citation index including citation context

A document, which may be referred to as a “citing document,” may include citations to one or more cited documents. An index of such documents may be referred to as a citation index or citator. Information used to present a citation index may be maintained in a computer-readable storage medium, and this information may include text in a citing document that immediately precedes a citation, immediately follows it, or both. Accordingly, one or more entries in a citation index may include display of one or more citations in the context in which the citations originally appeared. Computerized systems and methods for causing such display are also provided.
