Bolometric corrections are used in quasar studies to quantify total energy output based on a measurement of a monochromatic luminosity. We enumerate the practical difficulties of determining such corrections and present bolometric luminosities and corrections derived from the detailed spectral energy distributions of 63 bright quasars of low to moderate redshift. We explore several mathematical fittings to determine bolometric corrections and provide practical bolometric corrections of the traditional form as well as with an added constant at three wavelengths . The significant scatter in the 5100 angstrom bolometric correction can be reduced by adding a first order correction using the optical slope. We also provide X-ray bolometric corrections to the 2-10 keV luminosity. Finally, we recommend an adjustment to our bolometric corrections to account for viewing angle and the anisotropic emission expected from accretion discs.
