In "BASIC CONCEPTS OF ENRICHED CATEGORY THEORY", (version Reprints in Theory and Applications of Categories, No. 10, 2005), chapter 4.7 p.75-76, Kelly introduces the "discrete Grothendieck construction" in the case V=Set, and says that he'll treat the cases V=Gpd and V=Cat in an article "[46] G.M. Kelly, Categories with structure – biadjoints for algebraic functors, to appear."

I can't find this article under that name, does anyone have a reference for this?

Thanks!
