Research Impact: Personal impact

Making an impact and measuring the impact of your research

Author Identifer Tools

ORCID is an independent, open source system. It provides a persistent digital identifier that distinguishes researchers from others and  through integration in key research workflows such as manuscript and grant submission, supports automated linkages between you and your professional activities ensuring that your work is recognised.


Author identifier tools enable you to control your profile and overcome issues associated with variations of name spellings or institutions.

ResearcherID assigns a unique number to all researchers that links them with their published works. This is particularly useful in terms of any possible name variations or institutional affiliation changes. You can then update your profile information and build your publication list within your account using Web of Science or by uploading an EndNote file. ResearcherID also provides a variety of citation metrics including h-index, career citation count, citations per paper and collaboration metrics. If your subject area is well covered in Web of Science then its advantageous to use ResearcherID. However, ResearcherID does not automatically update with new publications, each author will need to keep their list/account up to date. If you leave the institution your account can be taken with you.


 How to register for ResearcherID

    When you log in using your ResearcherID and password, you will be taken to your own publications web page with a unique URL. You can include this link on your email signatures so that others can easily access your publications.

         A fact sheet about the resource is available as well as some videos.

         This reference card takes you through the steps to set up your account.

Scopus Author Identifier (Elsevier) helps to disambiguate author names. Using complicated algorithms the tool automatically matches variations of the author's name and distinguishes between authors with the same name. The algorithms behind the 'Author Identifier' assign a unique identifier number to each author whose published articles are covered by Scopus. Byusing these numbers, the algorithms review all variants of authors’ names and are able to match authors’ names with 99% accuracy.

  • Scopus allocates an 'Author Details' page to each author or researcher whose publications are covered by Scopus. This page then provides an overview of data associated with that author. There is also a feedback link which allows the author to check their details and tell Scopus if information needs to be amended or corrected. An overview of the product is available.

Measuring Individual, Author Impact

The H index measures the impact of an individual AUTHOR

You can calculate the h-index in databases such as web of Science and Scopus.

The g-index (Leo Egghe) is the (unique) largest number such that the top g articles received (together) at least g2 citations. It aims to improve on the h-index by giving more weight to highly-cited articles.


The m-index is defined as h/n, where n is the number of years since the first published paper of the scientist. It is more relevant to an earlier career researcher than the h-index
