In thermodynamic tables of liquids, S is usually given without mention of constant volume or constant pressure. In solids this makes sense because Cv ~ Cp, so S should be the same. In liquids, Cp > Cv especially as temperature increases, so I'd think that S would depend on constant pressure or constant volume conditions as well.

So my question is: is S the same at constant volume as it is at constant pressure?
