We report measurements of the proton form factors ${G}_{E}^{p}$ and ${G}_{M}^{p}$ extracted from elastic scattering in the range $1\ensuremath{\le}{Q}^{2}\ensuremath{\le}3$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$ with total uncertainties 15% in ${G}_{E}^{p}$ and 3% in ${G}_{M}^{p}$. Comparisons are made to theoretical models, including those based on perturbative QCD, vector-meson dominance, QCD sum rules, and diquark constituents in the proton. The results for ${G}_{E}^{p}$ are somewhat larger than indicated by most theoretical parametrizations, and the ratios of the Pauli and Dirac form factors ${Q}^{2}(\frac{{F}_{2}^{p}}{{F}_{1}^{p}})$ are lower in value and demonstrate a weaker ${Q}^{2}$ dependence than those predictions. A global extraction of the elastic form factors from several experiments in the range 0.1 $0.1{Q}^{2}10$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$ is also presented.
