Table 4: Non-ISI sources and incorrect journal abbreviations with more than
10,000 citations in the JCR 2005.

"With its 54,139 citations, the J Phys Chem-US would belong to the top-50
journals of the database if it were included. However, this journal is
included in the ISI-database under the abbreviations J Phys Chem A and J
Phys Chem B with 32,086 and 59,826 citations, respectively. For some
journals, however, the different spellings in the references may have large
implications. Bornman et al. (2007, at p. 105) found 21.5% overestimation of
the impact factor of Angewandte Chemie in 2005 because of authors providing
references to both the German and international editions of this journal
(Marx, 2001)."
