The {\it Herschel} Astrophysical Terahertz Large Area Survey (H-ATLAS) is asurvey of 660 deg$^2$ with the PACS and SPIRE cameras in five photometricbands: 100, 160, 250, 350 and 500\mic. This is the second of three papersdescribing the data release for the large fields at the south and northGalactic poles (NGP and SGP). In this paper we describe the catalogues offar-infrared and submillimetre sources for the NGP and SGP, which cover 177deg$^2$ and 303 deg$^2$, respectively. The catalogues contain 153,367 sourcesfor the NGP field and 193,527 sources for the SGP field detected at more than4$\sigma$ significance in any of the 250, 350 or 500\mic\ bands. The sourcedetection is based on the 250\mic\ map, and we present photometry in all fivebands for each source, including aperture photometry for sources known to beextended. The rms positional accuracy for the faintest sources is about 2.4 arcseconds in both right ascension and declination. We present a statisticalanalysis of the catalogues and discuss the practical issues -- completeness,reliability, flux boosting, accuracy of positions, accuracy of fluxmeasurements -- necessary to use the catalogues for astronomical projects.
