Scopus or Web of Science??Scopus Web of Science

Web of Science consists of nine databases containing information gathered from thousands of scholarly journals, books, book series, reports, conferences, and more.

• It fully covers over 12,000 major journals.• Create a visual representation of citation

relationships with Citation Mapping • Capture citation activity and trends graphically

with Citation Report • Use the Analyze Tool to identify trends and

patterns

Other databases?

Tasha received information that many of Ebsco & PQ databases offer citation analyses…I have no familiarity with these services.

Google Scholar is poised to become a player in this arena – Google Scholar Profiles are easy to use and harvest data automatically.

Google Scholar Metrics for Publications – released 4/1/2012

Part One

Attempt to assess the scholarly impact of a department (at Chair’s request).

If you plan to use Scopus, as I do, create an account to save your work….

Publication & Citation Counts

For a department…1. Decide on time frame to use – I use past year

(2011), past 5 years (2007-2011) and past 10 years (2002-2011).

2. Create & save a search (by affiliation):(AF-ID("Syracuse University" 60030551) OR AF-

ID("University Syracuse" 105277074) OR AF-ID("Syracuse University London Centre" 101417035)) AND ((dept* W/1 bio*) OR ("life science* complex")

OR (department W/1 biology))

Edit search with time frame:

(AF-ID("Syracuse University" 60030551) OR AF-ID("University Syracuse" 105277074) OR AF-ID("Syracuse University London Centre" 101417035)) AND ((dept* W/1 bio*) OR ("life science* complex") OR (Department W/1 Biology)) AND PUBYEAR IS 2010

Scopus has many help screens with useful information…

Check to make sure all pubs retrieved are from SU authors (may be grad students, postdocs, faculty, etc.)

Page 11: Citation Metrics

Linda Galloway

Select correct pubs and ‘View Citation Overview’

Save the list, so you can work with the data later: i.e. ‘Biology ‘2007

Export to RefWorks

• I also export the list of articles to a RefWorks account and share the link with faculty.

• Ask faculty to check to make sure all their publications are represented for each publication year.

• Send a summary report to chair

Further work:

• Can analyze the journal impact factors where author’s most frequently publish.

• Can compare publication rates, citation counts and impact factors to peer institutions.

• Many more things…

Choose ‘Author Search’ tab

Enter author’s name in in correct format. In most

cases, do not select ‘exact matches’.

Page 17: Citation Metrics

Scopus groups authors to aid in

disambiguation. In this example, both grouped authors are the same

person.

Page 18: Citation Metrics

Select author(s) and choose

‘Show Documents’

Page 19: Citation Metrics

Select only those articles attributable to author

What to do if you have more than one author profile in Scopus….

Page 23: Citation Metrics

Select YOUR author profiles – you may need to review all the articles associated with each author.

Page 24: Citation Metrics

Linda Galloway

Request to merge authors

Page 25: Citation Metrics
Page 26: Citation Metrics
Page 27: Citation Metrics
Page 28: Citation Metrics

Merge process may take up to 3 weeks – but it’s in your best interest to have

only one profile.

Pitfalls

• Depending on the data you retrieve, expect some unhappy customers…

• Be prepared to defend your data and methods• Pre-emptively communicate how and why you

collected the information you did• Stay strong!

Librarians

Rule!!
