Common Metrics

Publication count
The number of publications produced by an individual, department, etc.

Citation count
The number of times a publication is cited by other publications.

h-index
The h-index was devised in 2005 by Professor Jorge Hirsch, an American physicist, to measure the personal impact of researchers. It is defined as the largest number h, where a researcher has at least h publications cited at least h times. For example, someone with an h-index of 25 has written 25 papers which have each been cited at least 25 times.

Web of Science
The Web of Science consists of the Science Citation Index (1970 to date), the Social Sciences Citation Index (1970 to date) and the Arts & Humanities Citation Index (1975 to date). It indexes over 12,000 journals but the coverage of non-English language titles, conference papers and books is limited.

Scopus
Scopus covers over 20,000 journal titles and 6 million conference proceedings. It has better coverage of the social sciences and non-English language titles from Europe than the Web of Science. However, the citation data only covers papers published from 1996 onwards and the coverage of books is limited.

Publish or Perish
Publish or Perish was introduced in 2006 by Professor Anne-Wil Harzing from the University of Melbourne and can be downloaded for free. The data is taken from Google Scholar so a vast range of journal articles, conference papers, books, book chapters and other scholarly material is covered.  However, there is no source list for Google Scholar or indication of the timescale covered and as its content is generated automatically there are problems with data quality.

ORCID

ORCID is a free, non-profit author ID service. If you register, you will be assigned a unique, persistent identifier. This will enable you to distinguish yourself from every other researcher and avoid any confusion over authorship.
