Here is what I have, for science and library scholarly publishing. It's not "major STM publisher CEO blogging" but it's everything I've been able to find in this space so far.
"official" (i.e. posted in the publisher's DNS web domain)
- Nature http://blogs.nature.com/wp/nascent/ http://blogs.nature.com/nn/actionpotential/ http://blogs.nature.com/ng/freeassociation/ (see Dec 06, 2005 science publisher blogging)
- The Scientist http://www.the-scientist.com/blog/ (see Jan 05, 2006 life sciences blogging)
- Library Journal Tech Blog (see June 09, 2005 Library Journal gets bloggy with it)
unofficial / individuals
- Really Simple Sidi (Rafael Sidi, Elsevier)
- Lost Boy (Leigh Dodds, Ingenta)
- The Parachute (Jan Velterop, Springer)
- From the Hart (Clare Hart, CEO of Factiva)
- UPDATE 2006-01-15: Declan Butler suggests reporters should be included (Nature)
- UPDATE 2006-01-16: Joe Wikert (Wiley) via Really Simple Sidi
- UPDATE 2006-01-21: official blog of Richard Charkin (CEO, Macmillan) via Issues in Scholarly Communication
Inspired by some postings:
- Open Access News - Blogs by STM Publishers
- Really Simple Sidi - STM Publishers and Blogs
- Georgia State U - Issues in Scholarly Communication - Where are the official blogs of STM publishing executives?
There are certainly other types of publishing that use blogs. I read BusinessWeek Blogspotting amongst others.
For those of you clamouring for CEO blogging, here's a stat I found in Corporate blog survey
83% of the [executives] said their blogs were written or drafted by someone else, although they approved the text before it was published. Of the 17%, who said they wrote their own blogs, most said they first asked for advice from HR and communications colleagues.
