This book constitutes the refereed proceedings of the Third International Joint Conference on Electronic Voting, E-Vote-ID 2018, held in Bregenz, Austria, in October 2018. The 13 full papers presented in this volume were carefully reviewed and selected from 45 submissions. The papers deal with topics connected with electronic voting including experiences and revisions of the real uses of E-voting systems and corresponding processes in elections.

The last ten years have seen a gradual fragmentation of the Automated Reas- ing community into various disparate groups, each with its own conference: the Conference on Automated Reasoning (CADE), the International Workshop on First-Order Theorem Proving (FTP), and the International Conference on - tomated Reasoning with Analytic Tableau and Related Methods (TABLEAUX) to name three. During 1999, various members of these three communities d- cussed the idea of holding a joint conference in 2001 to bring our communities togetheragain.Theplanwastoholdaone-o?conferencefor2001, toberepeated ifitprovedasuccess.Thisvolumecontainsthepaperspresentedattheresulting event: the?rstInternationalJointConferenceonAutomatedReasoning(IJCAR 2001), held in Siena, Italy, from June 18 23, 2001. We received 88 research papers and 24 systems descriptions as submissions. Each submission was fully refereed by at least three peers who were asked to writeareportonthequalityofthesubmissions.Thesereportswereaccessibleto membersoftheprogrammecommitteeviaaweb-basedsystemspeciallydesigned for electronic discussions. As a result we accepted 37 research papers and 19 system descriptions, which make up these proceedings.

The third Workshop on Inference in Computational Semantics (ICoS-3) and the 9th Symposium on the Integration of Symbolic Computation and Mechanized Reasoning (CALCULEMUS-2001) were co-located with IJCAR 2001, and held their own associated workshops and produced their own separate proceedings."
