The main goal of this book is to describe the historical processes by which the Gibbs-Heaviside vector calculus became hegemonic in physics, beating out the rival systems of Grassman's exterior algebra (whose impenetrable texts won few converts) and Hamilton's octonians (which Gibbs and Heaviside basically cannibalised for parts, as Crowe makes clear).
Crowe's view of what counts as "modern" is pretty quirky though: he describes someone's treatment of linear vector functions by dyadics as "modern" and frankly I've never heard of that. (It seems to be an obsolete version of the tensor product, but trust me: this is not how it is taught now, or even back in the 1980s when I was an undergraduate.)
He discusses Clifford as a transitional figure but doesn't discuss Clifford algebra/geometric algebra in any detail (possibly not at all; I can't tell!). And Emil Cartan doesn't even rate an index entry!
In Crowe's account, the cross product is triumphantly Gibbs-Heavisidely a vector in 3-space, bi-vectors are banished and 3 space is really the only space that counts anyway and mathematicians versions of geometry are a niche interest of no particular relevance to his tale.
(It is, indeed, notable that both Gibbs and Heaviside were physicists, not mathematicians, and there decisive clout came from their successes in physics.)
Crowe's story ends in 1910 and takes it for more granted that nothing much has changed since. In fact there is, even in physics, a heterodox tradition (that of Flanders, Burke, and their followers) in which Cartan's differential forms - which build on Grassman's algebra and extend it with a notion of differentials that turns out to be exactly what you need to do integrations on manifolds, that has in the last century largely failed to have any impact on the undergraduate physics curriculum, although it is understood to be indispensible for serious geometrical work in physics.
