English abstract

We show that as a consequence of basic properties of elementary arithmetic journal impact factors show a counterintuitive behaviour with respect to adding non-cited articles. Synchronous as well as diachronous journal impact factors are affected. Our findings provide a rationale for not taking uncitable publications into account in impact factor calculations, at least if these items are truly uncitable.

Item type: Journal article (Print/Paginated)
Keywords: journal impact factor; arithmetic ; counter-intuitive behaviour
Subjects: B. Information use and sociology of information. > BB. Bibliometric methods.
