A brief description of the methodology of construction, contents and usage of the Planck Early Release Compact Source Catalogue (ERCSC), including the Early Cold Cores (ECC) and the Early Sunyaev-Zeldovich (ESZ) cluster catalogue is provided. The catalogue is based on data that consists of mapping the entire sky once and 60% of the sky a second time by Planck. A Monte-Carlo algorithm based on the injection and extraction of artificial sources into the Planck maps was implemented to select reliable sources among all extracted candidates such that the cumulative reliability of the catalogue is \gt=90%. As a result of the Monte-Carlo assessment of the reliability of sources from different techniques, the PowellSnakes source extraction technique was used at the 5 frequencies between 30 and 143 GHz while the SExtractor technique was used between 217 and 857 GHz. The 10 sigma photometric flux density limit of the catalogue at |b|\gt30 deg is 0.49, 1.0, 0.67, 0.5, 0.33, 0.28, 0.25, 0.47 and 0.82 Jy at each of the nine frequencies between 30 and 857 GHz. Sources which are up to a factor of 2 fainter than this limit, and which are present in ”clean” regions of the Galaxy where the sky background due to emission from the interstellar medium is low, are included in the ERCSC if they meet the high reliability criterion. The Planck ERCSC provides a robust list of stars with dust shells, stellar cores, radio galaxies, blazars, infrared luminous galaxies, Galactic interstellar medium features, 915 cold molecular cloud core candidates, 189 SZ cluster candidates as well as unclassified sources from the first high sensitivity radio/submillimetre observations of the entire sky. The source list, with more than 15000 unique sources, is ripe for follow-up characterisation.

Abstract
A brief description of the methodology of construction, contents and usage of the Planck Early Release Compact Source Catalogue (ERCSC), including the Early Cold Cores (ECC) and the Early Sunyaev-Zeldovich (ESZ) cluster catalogue is provided. The catalogue is based on data that consists of mapping the entire sky once and 60% of the sky a second time by Planck. A Monte-Carlo algorithm based on the injection and extraction of artificial sources into the Planck maps was implemented to select reliable sources among all extracted candidates such that the cumulative reliability of the catalogue is \gt=90%. As a result of the Monte-Carlo assessment of the reliability of sources from different techniques, the PowellSnakes source extraction technique was used at the 5 frequencies between 30 and 143 GHz while the SExtractor technique was used between 217 and 857 GHz. The 10 sigma photometric flux density limit of the catalogue at |b|\gt30 deg is 0.49, 1.0, 0.67, 0.5, 0.33, 0.28, 0.25, 0.47 and 0.82 Jy at each of the nine frequencies between 30 and 857 GHz. Sources which are up to a factor of 2 fainter than this limit, and which are present in ”clean” regions of the Galaxy where the sky background due to emission from the interstellar medium is low, are included in the ERCSC if they meet the high reliability criterion. The Planck ERCSC provides a robust list of stars with dust shells, stellar cores, radio galaxies, blazars, infrared luminous galaxies, Galactic interstellar medium features, 915 cold molecular cloud core candidates, 189 SZ cluster candidates as well as unclassified sources from the first high sensitivity radio/submillimetre observations of the entire sky. The source list, with more than 15000 unique sources, is ripe for follow-up characterisation.
