Usefull • Evaluation of academic reputation
for funders / employers
• Presenting your publication listfor other scientists to read/cite your papers
• Personal Scientific Brandingfor media /public/other science disciplines to find
you as an expert
• Web of Science / Google Scholarto improve their database

Differences
Database of origin Web of Science Google Scholar
Incorporated kind of publication & source
Selected Scientific only from Scientific journals
Scientific / Congress / Professional / websites/ undetermined
Errors and retraceability
Possible citation analysis
Sometimes missing metadata and source

Database & collection
‘It is the collection from the database that determines your citation metrics’
• the database is to register your publication
• the database is to register the publication that cites yours
• the citation report should contain the relevant publications
• the citation report should contain the relevant filters (years)

Notes
• “Combining citations from a largely unregulated space with a tightly regulated space is not just problematic, it corrupts the citation as an evaluative metric.”http://scholarlykitchen.sspnet.org/2012/12/12/gaming-google-scholar-citations-made-simple-and-easy/
• “This is not about competition, this is about providing an open platform for academic research,“http://www.nature.com/news/2011/110803/full/476018a.html
• “However, the h-index will vary considerably depending on a person's number of credited publications and the length of time they've been active”http://www.lib.utexas.edu/chem/info/cited.html

Choose between RID - GSC
• At NIOO we go for purely scientific = RID for official reports, Web of Science is leading
• At NIOO we care for our public image, therefore we encourage GSC as outreach tool

Citation reports for others
“ResearcherID and Google Scholar Citations can only be found if the author has activated them and made them public”
• ResearcherID’s database is Web of Science, only to be searched with subscription
• Google Scholar Citations’ database is Google Scholar and gives no metrics for other authors
except via Publish or Perish software tool

Conclusion (1)
‘Bottom-line:
Web of Science has the cleanest database, but is missing big chunks of scientific literature.
Google Scholar is the most complete, but has not merged slightly erroneous citations, and is cluttered with bogus information.’ http://gasstationwithoutpumps.wordpress.com/2010/06/30/google-scholar-vs-web-of-science/

Conclusion (2)‘Overall,
I trust Web of Science more, which is why I have been using it to compile citations to the 2003 NAR paper.
However, I use Google Scholar more frequently for quick reference simply because it is free and easy to access.’ http://xiang-jun.blogspot.nl/2011/07/tracking-3dna-citations-google-scholar.html
