Dear Colleagues,

As of 3 August 2012, the number of active peer-reviewed journals listed in
Ulrichsweb is 28,094 titles.  This figure represents a count of all Primary
editions (most of which are print, but some of which may be electronic) of
those titles.

The figure of 55,311 active peer-reviewed journals reflects the count of the
number of all related format editions of the 28,094 active peer-reviewed
journals. (For example, one of the 28,094 active peer-reviewed journals may
have a primary print edition, an online edition, and also a CD-ROM edition
for a total of 3 format editions.)

Dr. Harnad’s search results reflect the current count across all journal
format editions. It is possible to isolate (remove) the related editions
from those search results in Ulrichsweb by applying the Edition Type filter
on the Search Results screen and selecting that filter’s ‘Primary’ option.

We hope this information is helpful.
