This is the first paper in a series about our Multiwavelength Quasar Survey
. We give a detailed description of this survey and present the scientific
objectives, candidate selection procedures, and initial results of the obse
rvations of X-ray candidates in field f1002. Multiwavelength methods are em
ployed in order to reduce the selection effects. In this survey, we hope to
get a quasar sample more complete than that of any previous survey.
