Proton-nucleus collisions play an important role as a control system for
interpreting hot nuclear matter effects in $A+A$ collisions. Yet, there is a large amount of data from both RHIC and the LHC that indicate that collective effects are also present in such small systems. Understanding the origin of these effects is still incomplete, since a variety of models with very different underlying physics have been shown to describe $p+A$ data.

We present a comprehensive set of measurements of soft-physics observables and
detailed comparisons with theoretical models. These measurements include
$v_2(p_T)$ and $v_3(p_T)$ for inclusive and identified particles at mid-rapidity, $v_2(p_T)$ for hadrons and heavy-flavor muons at forward rapidity, multi-particle correlations as a function of event multiplicity, the centrality dependence of $dN_{ch}/d\eta$, and identified particle spectra. The implications for the origin of collectivity in $p+Au$ collisions at RHIC will be discussed.
