In Linear Algebra by Friedberg, Insel and Spence, the definition of span (pg-$30$) is given as: Let $S$ be a nonempty subset of a vector space $V$. The span of $S$, denoted by span$(S)$, is the set containing of all linear combinations of vectors in $S$. For convenience, we define span$(\emptyset)=\{0\}$. In Linear Algebra by Hoffman and Kunze, the definition of span (pg-$36$) is given as: Let $S$ be a set of vectors in a vector space $V$. The subspace spanned by $S$ is defined to be intersection $W$ of all subspaces of $V$ which contain $S$.
