ResumoPurpose The purpose of this conceptual paper is to present a simple, novel method for excluding self‐citation from h ‐index values – the b ‐index. Design/methodology/approach The work described assumes that relative self‐citation rate is constant across an author's publications and that the citation profile of a set of papers follows a Zipfian distribution, and from this derives a simple mathematical expression for excluding self‐citation from h ‐index values. Findings It is shown that this new index is simply equal to the integer value of the author's external citation rate (non‐self‐citations) to the power three quarters, multiplied by their h ‐index. This value, called the b ‐index, does not require an extensive analysis of the self‐citation rates of individual papers to produce, and appropriately shows the biggest numerical decreases, as compared to the corresponding h ‐index, for very high self‐citers. Practical implications The method presented allows the user to assess quickly and simply the effects of self‐citation on an author's h ‐index. Originality/value This paper provides a simple and novel method for excluding self‐citation from the h ‐index and should be of interest to those interested in bibliometrics and databases of scientific literature.
