  A framework is proposed for comparing different types of bibliometric
indicators, introducing the notion of an Indicator Comparison Report. It
provides a comprehensive overview of the main differences and similarities of
indicators. The comparison shows both the strong points and the limitations of
each of the indicators at stake, rather than over-promoting one indicator and
ignoring the benefits of alternative constructs. It focuses on base notions,
assumptions, and application contexts, which makes it more intelligible to
non-experts. As an illustration, a comparison report is presented for the
original and the modified SNIP (Source Normalized Impact per Paper) indicator
of journal citation impact.
