I am interested in fibrations of categories.Being a homotopy theoreticist I got acquainted with this subject through Ronnie BROWN's paper on fibrations of groupoids (1970). Can anyone help me to find recent papers on this subject ? Thanks for the trouble.

This may be a little outside your realm of interest, but it is very recent. Du\u{s}ko Pavlovi\'{c}'s thesis, "Predicates and Fibrations" includes a nice chapter on fibrations as variable categories. From the introduction to that chapter: ... The theory of fibrations, or fibered categories, is just category theory relative to a bse category. Ordinary categories can be viewed as fibered over 1. ==============================================================================
