In addition to the {\it semiclassical} Bekenstein-Hawking contribution to the area obtained earlier, we find a contribution proportional to the logarithm of the area together with subleading corrections that constitute a series in inverse powers of the area.4 pages in Revtex format, one eps figure; version published in Physical Review LettersGeneral Relativity and Quantum CosmologyHigh Energy Physics - Theorytext
