A plane graph G is entirely k-choosable if, for every list L of colors satisfying L(x)=k for all xϵV(G)∩E(G)∩F(G), there exists a coloring which assigns to each vertex, each edge and each face a color from its list so that any adjacent or incident elements receive different colors. It was known that every plane graph G with maximum degree Δ≥10 is entirely (Δ+2)-choosable. In this paper, we improve this result by showing that every plane graph G with Δ=9 is entirely 11-choosable.
