Bibliometrics in the libraryChances and pitfallsWouter Gerritsma, Wageningen UR
Evaluation cycle at universities Supervised by VSNU/QANU ● 6 year cycle for external peer reviews ● After 3 years midterm review ● Unit of analysis (in Wageningen): Graduate schools Citation analyses are not stipulated in the current Standard Evaluation Protocol. But have become mandatory at Wageningen UR, also at the social sciences department and for the research institutes
SEP criteria quality (including international academic reputation and PhD training) productivity (the relationship between input and output) societal relevance (including valorisation) vitality and feasibility (the ability to react adequately to important changes in the environment).
Current Research Information Systems Metis is a current research information system (CRIS) ● Information on all labour relations of all faculty and staff ● Information on all projects ● Information on all outputs (metadata of publications) ● Data entry at the chair group level ● Quality control by the library (inclusion of DOI)
Repository or Institutional Bibliography? Wageningen Yield (WaY) is the repository of Wageningen UR ● Synchronized overnight with the updates from Metis ● WaY contains metadata descriptions of all Wageningen UR publication output ● WaY is our OA repository

For a single publication Zee, F.P.v.d., G. Lettinga & J.A. Field (2001) Azo dye decolourisation by anaerobic granular sludge. Chemosphere 44:1169-1176. ● Citations from WoS: 94 Journal: Chemosphere Categorised by ESI in Environment/Ecology Baseline data for Environment/Ecology. ● Article from 2001 in Environment/ecology: ● On average: 19.36 citations; ● Top 10%: 44 citations; Top1%: 141 citations Relative Impact: 94 / 19.36 = 4.9
Advanced bibliometric indicators Follow Moed (1995) as closely as possible; but..... Web of Science is used for citation data ● We can’t make corrections for self citations Essential Science Indicators for baseline data (World average, Top 10% and Top 1%) ● Limited number of research fields (22) We can determine the representativeness of the citation analysis!
How to aggregate from a single publicationto an oeuvre? "CI" like indicator "MNCS" like indicator
Sources of citation data Web of Science Scopus Google Scholar Microsoft Academic SciFinder; Psychinfo ArXiv; Citeseer other open access repositories Other altmetrics initiatives
Web of Science Citation data (includes also citations from other databases on Wok) API to download citation data Baselines from ESI "New" product InCites ● Nijmegen has licensed InCites
Scopus Citation data obtainable through an API Benchmarking with SciVal Strata Not yet fully developed
Google Scholar Give them a few more years Coverage? Ghost citations Content duplication Benchmarking?

Why in the library? Library is the functional manager of Metis / WaY because of wide experience with bibliographic metadata Library manages contracts with publisher(s) of external databases that are being used Library has experience in developing and maintaining large databases Library has ample experience in searching complicated databases such as Web of Science
Advantage of using Metis / WaY Improvements in publication lists, etc. recorded Knowledge of, and experience with bibliometric analyses is better institutionalized Clarity / transparency for researchers Analysis of a single unit of the institute offers advantages for whole institute Better understanding of our own researchers ● We know where they publish ● We know what they cite ● We know something about their impact
Library outreach Improvement of the (meta)data quality in the repository Many presentations for research groups during the preparation for peer reviews Presentations based on detailed studies of single groups Library gives advice on publication strategies for groups and individuals ● there is a huge demand for these presentations Developed writing & citing courses with graduate schools
Closing the circle: Collection analysis With the coupling of publications with WoS We have gained insight in the relation ● Research group – Researchers – Publications – Reference list ● It is feasible to assign journal usage at faculty level, or more detailed (chair groups)
Lessons learned Start small, gain experience Show you can pull it off How much is your university spending on CWTS? Invest those resources in your own systems
