  This paper aims to investigate the extent to which researchers display
citation, and wants to examine whether there are researcher differences in
citation personal display at the level of university, country, and academic
rank. Physicists in 11 well-known universities in USA, Britain, and China were
chosen as the object of study. It was manually identified if physicists had
mentioned citation counts, citation-based indices, or a link to Google Scholar
Citations (GSC) on the personal websites. A chi-square test is constructed to
test researcher differences in citation personal display. Results showed that
the overall proportion of citation personal display is not high (14.8%), with
129 of 870 physicists displaying citation. And physicists from different
well-known universities indeed had a significant difference in citation
personal display. Moreover, at the national level, it was noticed that
physicists in well-known Chinese universities had the highest level of citation
personal display, followed by Britain and the USA. Further, this study also
found that researchers who had the academic rank of professor had the highest
citation personal display. In addition, the differences in h-index personal
display by university, country or academic rank were analyzed, and the results
showed that they were not statistically significant.
