Abstract: During most of ESA's Infrared Space Observatory (ISO) mission, the mid-infrared camera ISOCAM continued to observe the sky mainly around 6.7 microns in its so-called ``parallel mode'' while another instrument was prime. This permitted an unbiased survey of limited areas of the infrared sky, albeit with varying depth and wavelength per field due to the different instrumental configurations used and the highly variable time spent per pointed observation. To overcome the challenges of this unique survey, dedicated calibration, data reduction and source extraction methods were developed to analyze 6700 hours of these serendipitously recorded data. Over 42 square degrees of the sky could be processed and catalogued. We expect that the ISOCAM Parallel Source Catalogue will contain around 30000 sources, of which the weakest have fluxes of less than 0.5 mJy. The majority of these detections are new discoveries in the infrared.
