1. In the past, we have had quite some discussion regarding both open-access and open-access journals. However the slant in this blog post is different. I am not concerned here much about open-access journals per say.
Here, I am concerned about the policies that the prominent commercial journals keep regarding posting preprints on the Internet before these articles are submitted to them. I would like to know about policies kept in this regard by the commercial journals in the fields of physics, mechanics, and engineering (including software engineering, computational science and engineering, etc.).
