The Carnegie Supernova Project (CSP) is a five-year survey being carried out at the Las Campanas Observatory to obtain high-quality light curves of ∼100 low-redshift Type Ia supernovae (SNe Ia) in a well-defined photometric system. Here we present the first release of photometric data that contains the optical light curves of 35 SNe Ia, and near-infrared light curves for a subset of 25 events. The data comprise 5559 optical (ugriBV) and 1043 near-infrared (Y JHKs) data points in the natural system of the Swope telescope. Twenty-eight SNe have pre-maximum data, and for 15 of these, the observations begin at least 5 days before B maximum. This is one of the most accurate data sets of low-redshift SNe Ia published to date. When completed, the CSP data set will constitute a fundamental reference for precise determinations of cosmological parameters, and serve as a rich resource for comparison with models of SNe Ia.

• THE SPECTROSCOPIC DIVERSITY OF TYPE Ia SUPERNOVAE (2000, methodology): “…large sets of optical SN Ia light curves have already been published (Hamuy et al. 1996; Riess et al. 1999; Jha et al. 2006; Hicken et al. 2009; Contreras et al. 2010; Ganeshalingam et al. 2010; Stritzinger et al. 2011), but until the recent publication of 432 spectra of 32 SN Ia by Matheson…”
• The dependence of Type Ia Supernovae luminosities on their host galaxies (2010, methodology): “We construct a sample of low-redshift SNe Ia from the compilation of Conley et al. (2010), which includes SNe Ia from a variety of sources (primarily Hamuy et al. 1996a; Riess et al. 1999; Jha et al. 2006; Hicken et al. 2009a; Contreras et al. 2009).”
