A total of 167 data sets of composition- and temperature-dependent excess molar volumes, VE, which are derived from density measurements, for ionic liquid molecular solvent binary systems are inspected concerning their temperature dependence at fixed compositions. It is found that the VE temperature dependence is generally linear regardless of the sign and shape of the VE composition dependence. Plotting the slopes and intercepts of the linear VE temperature dependence as a function of composition allows for convenient comparisons of existing data sets. In doing so, VE data sets are critically examined with respect to data quality as well as obtaining insight into structure property relationships. This study also includes new density measurements for the binary systems 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide chloroform and 1-butyl-3-methylimidazolium methylsulfonate water, measured in the respective temperature ranges of (288.15 and 318.15) K and (298.15 and 358.15) K.
