Abstract: Scientometric studies on self-citations reveal variety of aspects, like attempted fraud approaching a
crime, a self-advertising tool, a standard scientific publication practice that saves space and time by reducing
repetitions, and so on up to self-citations being an important element of scientific networking. It seems, however,
that self-citation analysis will remain a hot topic for a long time mainly due to its effect on assessment of scientific
impact. Therefore, an obvious question that arises is, to what extent self-citations could modify the basic
scientometric indicators and indexes, used to perform such assessment.
This paper represents an attempt to quantitatively estimate the effect of self-citations on several widely used
scientometric indexes (Hirsch’s h, Egghe’s g and Zhang’s e). This has been achieved by incorporating selfcitations
into various explicitly given citation-paper rank distributions under more or less realistic assumptions.
The latter are deduced making use of well known empirical relationships, based on analyzing a considerable
amount of scientometric data. The results obtained contain self-citation corrections for the scientometric indexes,
as well as some indications for a ‘normal’ and ‘extraordinary’ self-citation behavior.
