As a comment on the subject of the following article
TITLE The rise and fall of uncitedness
> AUTHOR Schwartz CA
> JOURNAL COLLEGE & RESEARCH LIBRARIES 58: (1) 19-29 JAN 1997
I want to point out that there is another way of studying uncitedness. Indeed,
in a number of articles Leo Egghe, B. Gupta and I studied the first-citation
distribution. As a corrollary one obtains information about uncitedness,
because those articles that never obtain a first citation are simply those that
are not cited.
One important point though: the term 'uncited' has no meaning. One should
always add with respect to which database and which time period. 'Uncited in
the ISI database over the last 5 years' means something totally different
than 'uncited by your own department'.
