Citation Analysis

Article Citation Databases and Free Web Tools

The library licenses a growing number of databases, e.g. Compendex, PsycINFO, Academic Search Premier, IEEE, that offer citation counts from articles within that specific database. Check your discipline-specific databases to see if they provide citation counts.

Many databases provide options to create search alerts or citation alerts that will notify you when a new citation is entered. For more information on how to set up these alerts, please see the database Help screens or ask your subject librarian for assistance. 

In addition, free databases such as Google Scholar and Microsoft Academic Search trace networks of cited references and present them together. 

Author Metrics

The Hirsch index (h index) was proposed by J.E. Hirsch; it is defined as the number of papers with citation number ≥h, a useful index to characterize the scientific output of a researcher.

Databases with the h-index:

Journal Metrics

Journal metrics measure the performance and/or impact of scholarly journals. Each metric has its own particular features, but in general, they all provide rankings and insight into journal performance based on citation analysis.

Journal Impact Factor (JIF): For a journal to have an Impact Factor, it must be tracked by Thomson Reuters (ISI) for three years. Impact Factor information for journals is available through Journal Citation Reports database. 

The SCImago Journal Rank (SJR) is a free alternative journal citation metric based on citation information from Scopus.
