Why ask both for CV and publication list? Some academic job posts and grant applications require submitting both a CV and a publication list. I would have thought that it is a standard to put the publication list in the CV, hence it is not necessary to have the publication list again. What is the purpose of requiring both of them?
On mathjobs, my workflow when glancing through files from candidates is to look at the publication list instead of the CV.  This is for two main reasons:


CVs typically frontload a bunch of information which I already have from the mathjobs cover sheet (education, postdoc, advisors, etc).
CVs are longer than one page, so finding the publications takes some time.  Publication lists have the info I'm looking for right at the beginning.
