We explore the spectral energy distributions (SEDs) for 121,988 SDSS-selected quasars using mid-IR data from Spitzer, near-IR data from 2MASS and UKIDSS, optical data from SDSS, and UV data from GALEX. We consider the problem of determining bolometric corrections for individual quasars as opposed to the ensemble average. Significant differences can arise due to the fact that even the best observed SEDs have a gap of nearly 2 decades in frequency between the UV and X-ray. By fitting different quasar models in this region we find bolometric corrections can take on a range of values. We particularly consider the dependence of the bolometric correction on the UV luminosity and the properties of the CIV emission line. The latter can be used to distinguish between hard-spectrum radio-quiet quasars and soft-spectrum radio-quiet quasars, which can have very different bolometric corrections for the same UV luminosity and thus different Eddington ratios.
