Brief timeline for improved scholarly communication 1940’s Vannevar Bush 1940’s Vannevar Bush 1960’s & 1970’s Nelson, Engelbart, Licklider, van Dam 1960’s & 1970’s Nelson, Engelbart, Licklider, van Dam 1980’s Hypertext research field coalesces 1980’s Hypertext research field coalesces 1990’s Digital libraries and interactive digital storytelling research fields coalesce 1990’s Digital libraries and interactive digital storytelling research fields coalesce

5. Current practices of scholarly communication Focus on text and continuance of existing methods of writing the scientific record Focus on text and continuance of existing methods of writing the scientific record Restructuring old media via point-to-point conversions from the static physical world to a part of the digital world that is also static Restructuring old media via point-to-point conversions from the static physical world to a part of the digital world that is also static The way we make the record is essentially unchanged from Vannevar Bush’s time The way we make the record is essentially unchanged from Vannevar Bush’s time

6. A new approach to scholarly communication A wide-open exploration of the design space created by new media for writing the scientific record A wide-open exploration of the design space created by new media for writing the scientific record Focus on interactive authoring tools and systems that will help scholars record the record of their ideas and scientific contributions Focus on interactive authoring tools and systems that will help scholars record the record of their ideas and scientific contributions Authoring tools for the digital libraries of tomorrow Authoring tools for the digital libraries of tomorrow

7. Why are new forms of scholarly communication needed? Infrastructure is available: Infrastructure is available: Internet for dissemination Internet for dissemination Digital Libraries for archival storage Digital Libraries for archival storage Interactive faction is not keeping up with results from interactive fiction Interactive faction is not keeping up with results from interactive fiction Scholarly communication is already broken Scholarly communication is already broken Existing forms may not be the most efficient Existing forms may not be the most efficient New media may be more immersive and engaging New media may be more immersive and engaging

8. Plan of attack Draw upon our collective prior work on hypertext systems, interactive fiction, digital libraries, interactive digital storytelling, etc. to build an initial framework Draw upon our collective prior work on hypertext systems, interactive fiction, digital libraries, interactive digital storytelling, etc. to build an initial framework Refine and expand this framework through evaluations comparing the impact of different interactive media on scholarly communication Refine and expand this framework through evaluations comparing the impact of different interactive media on scholarly communication

9. Research agenda Design new systems for making and consulting the scientific record Design new systems for making and consulting the scientific record Evaluate and disseminate the results of interactive media studies on scholarly communication Evaluate and disseminate the results of interactive media studies on scholarly communication Generate and distribute new interactive media, authoring tools, and storytelling engines Generate and distribute new interactive media, authoring tools, and storytelling engines Improve the general framework for interactive scholarly communication Improve the general framework for interactive scholarly communication

10. Initial framework Interactive media tend to change the relationship between the reader and the author Interactive media tend to change the relationship between the reader and the author A simple model will suffice to discuss the design space of interactive scholarly communication A simple model will suffice to discuss the design space of interactive scholarly communication
