The talk will focus on logarithmic corrections to the area law for black hole entropy. Beginning with a sketch of the derivation of logarithmic corrections due to non-perturbative quantum spacetime fluctuations within a microcanonical ensemble, we will discuss its relation with logarithmic corrections arising from thermal fluctuations around an equilibrium canonical ensemble, for three and four dimensional asymptotically anti-de-Sitter black holes. We shall also briefly review the possibility of extending the analysis to asymptotically flat black holes.
