Sažetak
Aim To analyze the 2007 citation count of articles published
by the Croatian Medical Journal in 2005-2006 based
on data from the Web of Science, Scopus, and Google
Scholar.
Methods Web of Science and Scopus were searched for
the articles published in 2005-2006. As all articles returned
by Scopus were included in Web of Science, the latter list
was the sample for further analysis. Total citation counts
for each article on the list were retrieved from Web of Science,
Scopus, and Google Scholar. The overlap and unique
citations were compared and analyzed. Proportions were
compared using χ2-test.
Results Google Scholar returned the greatest proportion
of articles with citations (45%), followed by Scopus (42%),
and Web of Science (38%). Almost a half (49%) of articles
had no citations and 11% had an equal number of identical
citations in all 3 databases. The greatest overlap was found
between Web of Science and Scopus (54%), followed by
Scopus and Google Scholar (51%), and Web of Science and
Google Scholar (44%). The greatest number of unique citations
was found by Google Scholar (n = 86). The majority
of these citations (64%) came from journals, followed
by books and PhD theses. Approximately 55% of all citing
documents were full-text resources in open access. The
language of citing documents was mostly English, but as
many as 25 citing documents (29%) were in Chinese.
Conclusion Google Scholar shares a total of 42% citations
returned by two others, more influential, bibliographic resources.
The list of unique citations in Google Scholar is
predominantly journal based, but these journals are mainly
of local character. Citations received by internationally
recognized medical journals are crucial for increasing the
visibility of small medical journals but Google Scholar may
serve as an alternative bibliometric tool for an orientational
citation insight.
