WARPS is a serendipitous survey of relatively deep, pointed ROSAT observations for clusters of galaxies. The X-ray source detection algorithm used by WARPS is Voronoi Tessellation and Percolation (VTP), a technique which is equally sensitive to point sources and extended sources of low surface brightness. WARPS-I is based on the central regions of 86 ROSAT PSPC fields, covering an area of 16.2 square degrees. We describe here the X-ray source screening and optical identification process for WARPS-I, which yielded 34 clusters at 0.06<z<0.75. Twenty-two of these clusters form a complete, statistically well-defined sample drawn from 75 of these 86 fields, covering an area of 14.1 square degrees, with a flux limit of F(0.5x2.0keV)=6.5x10^-14^erg/cm^2^/s. This sample can be used to study the properties and evolution of the gas, galaxy and dark matter content of clusters and to constrain cosmological parameters. We compare in detail the identification process and findings of WARPS to those from other recently published X-ray surveys for clusters, including RDCS, SHARC-Bright, SHARC-south, and the CfA 160deg^2^ survey.2002ApJS..140..265Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/140/265CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/59 : the FIRST Survey, version 1999Jul (White+ 1999)J/ApJS/126/209 : Bright SHARC survey cluster catalog (Romer+, 2000)J/MNRAS/311/456 : RIXOS source catalogue (Mason+, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/140/265https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/140/265http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/140/265https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/140/265https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/140/265http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/140/265GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/140/265/table2 (WARPS-I Source Catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/140/265/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/140/265/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/140/265/table2?GETtext/xml+votable180.050000true2.1112520.5752780.005555555555555556Cone search capability for table J/ApJS/140/265/table3 (Other Sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/140/265/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/140/265/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/140/265/table3?GETtext/xml+votable180.050000true4.89458321.940.005555555555555556Cone search capability for table J/ApJS/140/265/table4 (WARPS-I Statistically Complete, Flux Limited Sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/140/265/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/140/265/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/140/265/table4?GETtext/xml+votable180.050000true17.9-38.1855560.005555555555555556Cone search capability for table J/ApJS/140/265/table5 (WARPS-I Additional Clusters and Candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/140/265/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/140/265/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/140/265/table5?GETtext/xml+votable180.050000true5.5141674.3772220.005555555555555556Cone search capability for table J/ApJS/140/265/table6 (Radio Sources within 2' of WARPS Cluster Candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/140/265/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/140/265/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/140/265/table6?GETtext/xml+votable180.050000true26.12454172.21202780.0055555555555555566/551 557 595 2340 8458 8555 8644 8673 8707 8908 8909 8922 8923 8944 9074 9080 9346 9666 9747 9750 9866 9882 9901 9903 9912 10305 10321 10529 10544 10774 10817 11017 11018 11371 11392 11457 12317 12407 13389 13391 15260 15261 17192 17730 17749 17751 17850 17866 18111 18112 18113 18324 18325 18524 18642 18660 18682 18683 18703 19151 19283 19886 19897 19975 20023 20097 20099 20311 22544 22660 25102 26022 26370 26443 26554 27191 27234 30028 30029 30833 33378 33713 33716 34570 35272 35446 35447 36132 36212 36214 36342 36545 36547 36771 36772 36774 44785 44993 48595 48598 48926 49112 49113https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/140/265?format=asciiX-raydefault
