From extensive follow-up observations of 136 candidate objects, we find 36 lenses in the full sample of 77,429 spectroscopically confirmed quasars in the SDSS Data Release 5. Description: The 136 lensed quasar candidates taken from the 13,636 quasars constitute our targets for follow-up observations, but we remove two candidates that have already been examined. One is the morphologically selected candidate SDSS J111816.95+074558.1 which is the well-known lensed quasar PG1115+080 (Weymann et al. 1980Natur.285..641W). The other is the color-selected candidate SDSS J165502.02+260516.5, which is a pair of quasars with slightly different redshifts from SDSS spectroscopy. The remaining 134 candidates were observed as described in what follows using various telescopic facilities. The observations include optical and/or near-infrared imaging and optical spectroscopy, and are tabulated in Tables 2 and 3. File Summary:
