The selection is carried out using direct plates obtained at the ESO and UK Schmidt Telescopes, scanned with the COSMOS facility and searched for objects with an ultraviolet excess. Follow-up spectroscopy, carried out at ESO La Silla, is used to classify each candidate. In this initial paper, we describe the scientific objectives of the survey; the selection and observing techniques used. We present the first sample of 285 QSOs (M_B_<-23) in a 153 sq.deg area, covered by the six "deep" fields, intended to obtain significant statistics down B=~18.75 with unprecedented photometric accuracy. From this database, QSO counts are determined in the magnitude range 17<B<18.75.1995A&AS..112..347Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/112/347CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/112/347https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/112/347http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/112/347https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/112/347https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/112/347http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/112/347GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+AS/112/347/f287 (List of candidates and their spectroscopic identification: Field 287)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/112/347/f287?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/112/347/f287?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/112/347/f287?GETtext/xml+votable180.050000true319.8207755-45.49715320.005555555555555556Cone search capability for table J/A+AS/112/347/f351 (List of candidates and their spectroscopic identification: Field 351)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/112/347/f351?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/112/347/f351?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/112/347/f351?GETtext/xml+votable180.050000true9.0484164-35.12479680.005555555555555556Cone search capability for table J/A+AS/112/347/f534 (List of candidates and their spectroscopic identification: Field 534)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/112/347/f534?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/112/347/f534?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/112/347/f534?GETtext/xml+votable180.050000true339.0868778-23.7959670.005555555555555556Cone search capability for table J/A+AS/112/347/fsa94 (List of candidates and their spectroscopic identification: Field SA94)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/112/347/fsa94?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/112/347/fsa94?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/112/347/fsa94?GETtext/xml+votable180.050000true40.15737590.18875890.005555555555555556Cone search capability for table J/A+AS/112/347/fsgp (List of candidates and their spectroscopic identification: Field SGP)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/112/347/fsgp?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/112/347/fsgp?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/112/347/fsgp?GETtext/xml+votable180.050000true10.748512-30.12881870.005555555555555556Cone search capability for table J/A+AS/112/347/f295 (List of candidates and their spectroscopic identification: Field 295)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/112/347/f295?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/112/347/f295?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/112/347/f295?GETtext/xml+votable180.050000true9.7627153-39.62537130.0055555555555555565/0 2 4160-4161 4163-4164 4256 4436-4438 8859 8880-8881 8883-8884 8887 8889 8893 8937 8939 8942 9214-9215 11683-11684 11743 11765 6/6 12 16469 16649 16660 16664 16936 16938 17030 17032 17733-17735 17741 17756-17758 17777 17780-17782 35391 35427 35429-35431 35433-35435 35440 35442 35448-35450 35454 35477 35479 35528-35529 35531 35542 35544-35546 35565 35569-35570 35576-35578 35580 35722-35723 35747 35753-35755 35762 35774 36854 46637-46639 46648 46650-46651 46721 46723-46725 46728-46729 46740 46744 46967 46969-46971 47047 47056-47057 47065 47067-47068 47070-47071https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+AS/112/347?format=asciiOpticaldefault
