Abstract: 
Experimental searches for modifications of vector mesons in the nuclear medium are reviewed. Data on rho, omega and Phi mesons are presented. The results have been obtained in elementary reactions with proton and photon beams as well as in heavy-ion collisions. Compared to the free particle properties, the omega and Phi mesons are found to have a drop in mass at normal nuclear matter density by 9%-14% and 3.5% whereas their widths are reported to increase by factors of about 16 and 3.6, respectively. For the rho meson, conflicting results on in-medium mass shifts and broadening have been published. The experimental data are compared to recent model calculations.
