I’ve successfully used Thomson’s InCites to perform publication/subject analysis for my previous employer, such as subject area strengths and citation impact against national and international benchmarks. You can do this at the institutional, departmental or individual level, but it too has its limitations, such as limited data sets.

Dear Wouter,

Many thanks indeed for responding to me so promptly and for sending such an informative email. I had my suspicions about the Crown indicators and your email helps to confirm these! Thanks again - much appreciated,

Kind regards

Lorraine

Dear Lorraine

The wisest is to abandon the Crown Indicator althogether.

The CI had come under a lot of criticism in 2010 and the impression I have is that CWTS has carried the CI to its grave in 2011.

Dear Colleague,

I am seeking basic advice on Crown indicators and would greatly appreciate if you could email me by return if you are currently using this model in publication/subject analysis of your organisation. With many thanks in advance,
