The following paper is available by anonymous ftp: Remarks on the Theory of Semi-Functors R. Hoofman & I. Moerdijk Abstract: "By establishing an appropriate equivalence, we show that the theory of semi-functors can be fully embedded in the theory of (ordinary) functors. As a result, standard properties and constructions on functors extend automatically to semi-functors." FTP instructions:
