They should be used as a supplement to traditional metrics. Alternative measures can assist:
: can accumulate more quickly than traditional metrics such as citations
: can be gathered for many types of research outputs, not just scholarly articles
: can give a fuller picture of research impact using many indicators, not just citations
t: can measure impact outside the academic world, where people may use but not formally cite research
: If researchers get credit for a wider range of research outputs, such as data, it could motivate further sharing
