Notes From the Library…Author Identifiers

What are author identifiers?

An author identifier is a unique identifier that distinguishes one researcher from another, eliminating confusion in scholarly publication and grant funding.

Why do we need author identifiers?

If you have ever tried to do an author search a database, then you know how difficult it can be to find all articles by a particular author.  An author may have a common surname, publish under variations of the same name, change their name, or different geographical/cultural conventions for reporting their name.  Affiliation and field of study relieve some of the ambiguity associated with author names, but inclusion of this information in a search does completely eliminate the problem.  Two authors with the same name may work in the same field.  Like author names, there are often multiple ways to list the name of a department, school or university, and affiliations change as an author moves from one institution to another.  Moreover, some databases only provide the affiliation of the first author, or allow an author to list only one affiliation.  PubMed/MEDLINE did not include affiliation for all authors until 2014.  For these reasons, a simple search for articles by one author can easily become complicated.

What options exist for author identifiers? 

Over the past few years, one author identifier system has emerged as the frontrunner: Open Researcher and Contributor ID, or ORCID (http://orcid.org/).  ORCID is an open, non-profit community effort that provides unique persistent digital identifiers for researchers.  ORCID partners and members include universities, commercial research organizations, publishers, professional societies and funders, such as Nature Publishing Group and the National Institutes of Health (NIH).  Several publishers offer the option of including an ORCID ID when submitting an article, and some plan to make an ORCID ID mandatory for corresponding authors (http://blogs.plos.org/plos/2016/01/author-credit-plos-orcid-update/).

A few publishers have their own author identifier system.  For example, when researchers register for Thomson Reuters free online community, ResearcherID, they are assigned a unique alphanumeric identifier that can be used to track their publications and get citation metrics in Web of Science.  Authors of articles indexed in Scopus, an Elsevier database, are automatically assigned a unique identification number.

This sounds like one more account to maintain, do I really need an author identifier?

Yes, an ORCID ID is another account to create and maintain.  However, ORCID has gained traction amongst universities, publishers and funders, and if this pattern continues, then hopefully it will alleviate author ambiguity.

Any researcher can register for a free ORCID ID.  You can use your Tufts username and password to register for, or link to an existing, ORCID ID.  To get started, go to this page: https://orcid.org/signin.  Choose to sign in using your institutional account and search for Tufts.  You will be prompted to enter your Tufts username and password.  Once you do so, select the ‘Register for an ORCID ID’ link.  For more information about creating and managing your ORCID account, see: http://support.orcid.org/knowledgebase/topics/32827-using-the-orcid-registry.

Notes From the Library…Measuring Research Impact: Altmetrics

What are altmetrics?

The graduate student who coined the term ‘altmetrics’ in a 2010 tweet has defined altmetrics as “the study and use of scholarly impact measures based on activity in online tools and environments” (Priem, 2012).  The term is often used to describe any alternative, non-citation based measure of research impact, such as:

  • Number of times an article has been viewed or downloaded from a journal website, or database
  • Number of times an article has been exported to a citation manager
  • Number of times an article has been shared via email or on Twitter, Facebook or other social media sites
  • Mentions in the mainstream media

How are altmetrics different from traditional citation metrics?

Altmetrics are generated rapidly, as opposed to citations which take time to accumulate.  Altmetrics capture data from a variety of sources, both within and beyond the scholarly community, versus traditional citations, which only capture information from published scholarly works.  Altmetrics also recognize research products beyond the peer-reviewed journal article, such as data sets and code (Khodiyar, Rowlett and Lawrence, 2014).

Where can I find altmetrics? 

Look for altmetrics when viewing an article on a journal’s website:  Many publishers, such as PLoS, provide the number of times an article has been viewed, shared, saved or download from their site.

Look for an Altmetric score: Altmetric (http://www.altmetric.com/) monitors online activity for mentions of scholarly articles.  The collected data is used to calculate an Altmetric score, a measure of the quality and quantity of attention that an article receives.  A recent article in the Annals of Emergency Medicine describes how the Altmetric score is calculated, and the potential impact and limitations of this score.

Install the free Altmetric bookmarklet to get stats for an article you are reading online, or look for an Altmetric score Altmetric Score when viewing articles on:

  • A journal’s website
  • JumboSearch: Copy and paste the title of an article into our library’s search tool, JumboSearch (http://tufts.summon.serialssolutions.com/). If an Altmetric score is available for the article, then you will see an Altmetric Box icon  below the abstract.
  • Scopus: Scopus is a database that indexes journal articles, conference proceedings and books from the sciences, social sciences, art and humanities. When viewing an article abstract in Scopus, look for the Metrics box in the right-hand column.

Impactstory: Impactstory (https://impactstory.org/) is a web-based tool that gathers metrics on research products (articles, data sets, etc.) from a variety of sources, including Facebook, Google+, Twitter and PubMed Central.  Impactstory profiles display raw numbers as well as badges that indicate how a product has performed compared to similar products in the same discipline.  Individuals with an ORCID (Open Researcher and Contributor ID) can create an Impactstory profile for free.

So, what do these all this mean?

Altmetrics are an evolving area of use and study.  Altmetrics provide a more nuanced picture of how articles are being used, and therefore compliment, not replace, traditional measures of research impact.  For more on altmetrics, see ‘Research Impact: Altmetrics Make their Mark’ from Nature, and ‘Rise of “Altmetrics” Revives Questions about How to Measure Impact of Research’ from The Chronicle of Higher Education.
