Bibliometrics (and altmetrics) are ways to measure and compare research publications, authors, departments, and institutions. These metrics allow one to 

  • Find the best journals in a field
  • Find how often an article is cited
  • Determine highly cited articles and authors in a field

Bibliometrics affect

  • Researchers and authors
  • Library journal collections
  • Research funding
  • Tenure and promotion
  • Expertise status in the field
  • Finding others in a field/subject area
  • Journal metrics

    Journal metrics allow comparison of journals for purposes of 

    • Choosing a journal in which to publish
    • Comparing journal performance and trends
    • Evaluating publications in these journals
  • Article metrics

    Article metrics attempt to measure the research impact of articles (and their authors).

  • Book and book chapter metrics

    Citations for books and book chapters are not tracked as well as journal articles. In some disciplines, book reviews (and where those reviews were published) may be more important than cited references. These tools may be more useful than the traditional cited reference tools.

  • Author metrics

    Author metrics attempt to measure and compare researcher impact. One of the primary author metrics is the h-index, which combines productivity and impact measures. Alternative metrics include

    • g-index, which weigh highly-cited papers more heavily
    • hi-index, which takes the number of co-authors into account
    • hc-index, which weighs newer articles more heavily than older articles
    • m-index, which takes career length into account
  • Altmetrics

    Alternative metrics of impact or altmetrics are a new way to measure and track the social impact of research in real time. Altmetrics track research uptake via social media, citation counting, mentions or bookmarks, attention to high profile blogs, and even Wikipedia references. Altmetrics allows us to expand our view of what's making the impact and what it looks like in a scholarly environment that is becoming more diverse.
  • Publish or perish tool

    Publish or perish tool is a software program that retrieves and analyzes academic citations. It uses Google Scholar and Microsoft Academic Search to obtain raw citations, then analyzes these and presents a variety if bibliometrics.

  • Ranking researchers and institutions

    As more research literature is published online, the ability to analyze relationship among these publications has become easier. There are several tools that can be sued to analyze and rank these relationship (though Virginia Tech does not subscribe to all of them).
