Citation Frequency and Ethical Issue

Dear Editor:

I read your publication ethics issue on “bogus impact factors” with great interest (1).
I would like to initiate a new trend in manipulating the citation
counts. There are several ethical approaches to increase the number of
citations for a published paper (2). However, it is apparent that some manipulation of the number of citations is occurring (3, 4). Self-citations, “those in which the authors cite their own works” account for a significant portion of all citations (5).
With the advent of information technology, it is easy to identify
unusual trends for citations in a paper or a journal. A web application
to calculate the single publication h-index based on (6) is available online (7, 8). A tool developed by Francisco Couto (9)
can measure authors’ citation impact by excluding the self-citations.
Self-citation is ethical when it is a necessity. Nevertheless, there is a
threshold for self-citations. Thomson Reuters’ resource, known as the
Web of Science (WoS) and currently lists journal impact factors,
considers self-citation to be acceptable up to a rate of 20%; anything
over that is considered suspect (10).
In some journals, even 5% is considered to be a high rate of
self-citations. The ‘Journal Citation Report’ is a reliable source for
checking the acceptable level of self-citation in any field of study.
The Public Policy Group of the London School of Economics (LSE)
published a handbook for “Maximizing the Impacts of Your Research” and
described self-citation rates across different groups of disciplines,
indicating that they vary up to 40% (11).
Unfortunately,
there is no significant penalty for the most frequent self-citers, and
the effect of self-citation remains positive even for very high rates of
self-citation (5). However, WoS has dropped some journals from its database because of untrue trends in the citations (4).
The same policy also should be applied for the most frequent
self-citers. The ethics of publications should be adhered to by those
who wish to conduct research and publish their findings.
