Classification of exterior and proper fibrations
We classify exterior fibrations in the exterior homotopy category. As a result we also classify proper fibrations between CW-complexes.

A note on covers defining relative and sectional categories
We give a characterization of relative category in the sense of Doeraene-El Haouari by using open covers. We also prove that relative category and sectional category can be defined by taking arbitrary covers (not necessarily open) when dealing with ANR spaces.
