Definition 64.12.5. Let $S \in \mathop{\mathrm{Ob}}\nolimits (\mathit{Sch}_{fppf})$ be a scheme. Let $F$ be an algebraic space over $S$. A Zariski covering $\{ F_ i \subset F\} _{i \in I}$ of $F$ is given by a set $I$ and a collection of open subspaces $F_ i \subset F$ such that $\coprod F_ i \to F$ is a surjective map of sheaves.

The third sentence is awkward; maybe delete the comma and replace it with the word "and?"
