How best to present publications in different areas on a CV? I am trying to list my publications in my curriculum vitae. But, because I have publications in three fields x, y, z of study such that x is my major and y, z are not, I am looking for how to best display them so that it can be emphasized that I have works in different areas.
Why not just make three lists of publications (one for each field) and place each with its own subheading under the general heading "Publications"?

i.e.:

Publications

Biology


pub 1
pub 2


Astronomy


pub 1


Mathematics


pub 1
pub 2
