We review the level spectroscopy, which is a powerful method of analyzing thenumerical data with respect to the Berezinskii-Kosterlitz-Thouless quantumphase transition in one dimension. We focus on its physical meaning and alsoits application to the magnetization plateau problems.Comment: 6 pages, 3 figures (embedded), Conference paper: Yukawa-Institute-for-Theoretical-Physics International Workshop "Order, Disorder, and Dynamics in Quantum Spin Systems" (Nov.15-16,2001): will be published as a special issue of Supplement Prog. Theor. Phys. Several refereces are added and typos are correcte
