Traditional bibliometrics: tools & services

VU Library offers various tools & services for traditional bibliometrics.

Please note: the outcome of a metric analysis depends on which database you use.

* Citation analysis – You can find out how many times your publications have been cited on journal and citation indexes such as Scopus, Web of Science, Google Scholar

* H-index or Hirsh-index: measures both the productivity and the impact of the published work of a researcher. The definition of the index is that a scholar with an index of h has published h papers each of which has been cited in other papers at least h times. A H-index of 12 means there are 12 published papers each with at least 12 citations.
- In some disciplines the H-index is used to indicate the level of seniority in one’s academic career. The bandwidth differs per field of research.
- You can use Scopus to calculate your H-index.
- As a paid service (on request) VU Library can calculate the H-index for you for human resource evaluations based on Web of Science.

* Journal Impact Factor: the impact of a journal is indicated by calculating the average number of times articles published in that journal have been cited over the past five years.
- It indicates the importance or rank of a journal.
- VU Library’s shows you the impact factor (for Scopus and Web of Science) for the most important journals in your field.
- With Scival you can also benchmark the journals your department publishes in.

* Field Weighted Impact Score: this metric indicates how the number of citations received by a researcher’s publications compares with the average number of citations.
- Shows you how many times you or your department scores below or above worldwide average, for one or more research fields.
- You can use Scival (based on Scopus) or the Essential Science Indicator-ESI (combined with Web of Science). With SciVal you can select publications from PURE, and see the field weighted impact in a few clicks. With ESI you have a base line table where you can calculate field weighted impact by yourself.

* CiteScore: this indicates the merit of an individual paper over the past three years (based on Scopus)
- Shows you the development in use of your paper in academic literature since publication.
- You can use Scopus to see the trend in your citation score.

* Eigenfactor: this indicates the impact of a journal in a network (based on Web of Science).

* Scival In 2018 VU Library offers VU researchers Scival. This is a citation analysis tool that helps you to evaluate and compare research, using citation and usage data from Scopus and Science Direct. It can be used to help assess the research performance of institutions, research groups or individual authors, or to identify influential journals or research areas.
It also enables you to visualize research performance, benchmark relative to peers and identify collaborative networks.
