transfer models of starless cores using 450 and 850 [$\mu$m]{} data from the SCUBA archive (Y. Shirley et al. 2006, in preparation). This is by no means a complete list of projects in which continuum and molecular line data on these cores can be found, especially for the cores in Perseus since many recent studies have focused on that region (e.g., Enoch et al. 2006; Kirk et al. 2006); it is only meant to compare the cores observed in this survey with other, complementary programs currently in progress.

As of November 2005, we have mapped 52 cores at 350 $\mu$m and three at 450 $\mu$m, two of which were observed at both wavelengths. Out of the 53 unique cores observed here, 18 are included in the SCUBA survey, 16 are included in the MAMBO survey, 6 are included in the SIMBA survey, 18 are included in the FCRAO survey, and 7 are included in the radiative transfer modeling project by Y. Shirley et al. (2006, in preparation).

Observations {#subobs}

Observations were conducted in May and September of 2003, June and September of 2004, and March, June and November of 2005 at the CSO. We used the sweep mode of
