Personal Citation Index

[Judit Bar Ilan]

Ronald Rousseau's numbers are not based on anecdotal evidence only.
Although I was not looking for personal citations, I conducted a rather
exhaustive search for "informetrics" in 1998.
(The results are published in JASIS, 51(5) - The Web as an information
source on informetrics? A content analysis).

 From the collected pages I extracted 259 distinct references (to journal
papers, papers in proceedings and to presentations in conferences). Since
most of the references in the Web appeared without abstract (or full text),
for 229 references, the term "informetrics" either appeared in the title
(75) or in the name of the publication (154).

These references were compared to data retrieved from commercial
bibliographic databases: the largest number of items with informetrics in
the title was retrieved from LISA (46 vs 76), and the largest number of
items retrieved with informetrics in the name of the publication was
retrieved from OCLC's PaperFirst Database (118 vs 184). These numbers seem
to support Ronald Rousseau's 50% assumption.
