The conference was heldinViennafrom17thto19thofSeptember,2001. Itwascollocatedwiththe JointGerman/AustrianConferenceonArti'cialIntelligence(24thGerman/9th AustrianConferenceonArti'cialIntelligence),KI2001. LPNMR conferences aim to promote research in logic-based programming languages, database systems, nonmonotonic reasoning, and knowledge rep- sentation. LPNMR2001 was the sixth conference in the series. The previous meetingswereheldinWashington,DC,in1991,inLisbon,Portugal,in1993,in Lexington,Kentucky,in1995,inDagstuhl,Germany,in1997,andinElPaso, Texas,in1999. ThetechnicalprogramofLPNMR2001wascomprisedof'veinvitedtalks thatweregivenbyJur ¨ genDix,GeorgGottlob,PhokionKolaitis,MaurizioLe- erini,andChiakiSakama. Italsocontained23technicalpresentationsselected bytheprogramcommitteeduringarigorousreviewprocess. Finally,asapart ofthetechnicalprogram,theconferencefeaturedaspecialsessioncomprisedof ninepresentationsanddemonstrationsofimplementednonmonotonicreasoning systems.
