The increase of publications about bibliometrics as indexed by Web of Science between 1994 and 2014 (data retrieved from Web of Science on 9 February, 2015).

Goodhart’s Law: When a measure becomes the target, it ceases to be a good measure

Goodhart, 1975

Outreach and Impact Leader, - Ref:1455401

“ We are seeking to recruit … to support, develop and promote outreach and impact activities …Our aim is to maximize the widest possible impact of the research programme in whichever way is most appropriate … The salary range will be £41,430 - £48,873 per annum...”

Project is financed by the Ministry of Education and Culture in Finland (2015-2016)

Goals of the research project:1) Investigate altmetrics (at country-level, i.e.

Finland) and create a prototype to demonstrate them

2) Develop methods to map societal impact of research (and to analyze the stories behindthe altmetrics)
