[Further corroborative data from Carol Tenopir that Ulrich's
covers 24K peer-reviewed journals, of which 18K are
self-described as "scholarly/academic." Still a mystery what
fields the other 6,000 peer-reviewed journals are in! -- SH]

Stevan, You are right that the exact number of journals depends on the
search strategy, version of Ulrich's used (and even Ulrich's indexing
policies). To avoid the problem of spurious accuracy is why I now always
do as you do and round the number off. I check this every 6 months or so
(last time for part of the strategies was a few weeks ago). Attached are
the Feb. 2003 and Oct. 2003 counts from ulrichsweb with the stategies
given (there are many ways to slice this cake.) Carol

Definitions from the Ulrich's online glossary:
Active: A publication status that indicates that a title is currently
being published.
Refereed: Otherwise known as peer-review. Refers to the system of
critical evaluation of manuscripts/articles by professional colleagues
or peers. The content of refereed publications is sanctioned, vetted, or
otherwise approved by a peer-review or editorial board. The peer-review
and evaluation system is utilized to protect, maintain, and raise the
quality of scholarly material published in serials. Publications subject
to the referee process are assumed, then, to contain higher quality
content than those that aren't.
