A new general method for the determination of the work of critical cluster formation in nucleation theory is developed. The method consists in a generalization of Gibbs' approach retaining its advantages and avoiding some of its shortcomings. For small supersaturations, the results are in agreement with the classical Gibbs' approach (when in Gibbs' method, in addition, the capillarity approximation is employed). However, in contrast to the classical and in agreement with van der Waals' type approaches to the determination of this quantity, for initial states near the spinodal curve the work of critical cluster formation is shown to tend to zero.
