The world experimental data on cross section and kinematic distribution in p+p and p+A collisions at s√ = 6.8 - 7000 GeV are examined in systematic way. The s√ dependence of the inclusive cross section, rapidity and transverse momentum distributions are studied phenomenologically. We explore empirical formulas to obtain the total cross section, rapidity and transverse momentum (pT) distribution. This is crucial for the interpretation of A+A J/ψ results at RHIC when the p+p reference data are not available. In addition, the cross section at mid-rapidity and transverse momentum distributions in p+p collisions at s√ = 39 and 62.4 GeV are evaluated.
