I'm currently in the process of writing a literature review for a methodology and I came across two relevant works by the same author. The first is their dissertation which includes expanded details about their research questions the methodology they developed to address the research questions. The second work is a publication that is based upon one research question and doesn't contain as much detail about they methodology. My instinct is to cite both,
method is used by Author et al. (YYYY) in an evaluation of system, which is described in more detail in (Author YYYY).
but generally it seems like only the publication is cited if available. Is it preferable to cite the dissertation or a publication based on the dissertation, or both?
