This paper details a proof of concept for a new paradigm for the creation and maintenance of TEI conformant, SGML-based electronic editions of historical literature. The Just In Time Markup (JITM) paradigm as described in this report, solves a number of common problems identified in the systems currently in use for creating electronic editions. The report also shows how the nature of the JITM paradigm will reduce the significant workload involved in creating and authenticating an edition while allowing the edition to be a continually evolving research work for any number of scholars even after publication. Unlike the current systems in use for creating electronic editions, the nature of the JITM paradigm also protects the digital asset of the transcription of the original states of the work, preventing the possible proliferation of variant states of the electronic edition.
