3. Motivation The Goal: To improve the method used by Astrophysics researchers for searching the ADS to locate papers of interest The Goal: To improve the method used by Astrophysics researchers for searching the ADS to locate papers of interest The Problem: ADS results are returned in a text format that is useful for individual queries but is difficult to use in constructing reference or citation chains The Problem: ADS results are returned in a text format that is useful for individual queries but is difficult to use in constructing reference or citation chains The Solution: Provide researchers with a graphical method for searching the ADS The Solution: Provide researchers with a graphical method for searching the ADS Must be intuitive to use Must be intuitive to use Paper relationships should be clearly indicated Paper relationships should be clearly indicated Search tools should be simple Search tools should be simple ADASS XVII, London, September 26, 2007

4. Solution: PaperScope PaperScope is a standalone application built for graphically exploring the ADS PaperScope is a standalone application built for graphically exploring the ADS Provides tools for graphing ADS search results into a 2D graph of nodes (papers) and edges (relationships) all in real time Provides tools for graphing ADS search results into a 2D graph of nodes (papers) and edges (relationships) all in real time The graph can be expanded by querying the ADS for reference or citation lists (or both) for a chosen paper The graph can be expanded by querying the ADS for reference or citation lists (or both) for a chosen paper The graph can be searched and manipulated to locate papers of interest The graph can be searched and manipulated to locate papers of interest A graph can be saved to a file for later use or for distribution A graph can be saved to a file for later use or for distribution ADASS XVII, London, September 26, 2007

11. Main Uses Researching reference and citation chains for a particular paper Researching reference and citation chains for a particular paper Identifying common (i.e. important) references for papers in a particular field Identifying common (i.e. important) references for papers in a particular field Sharing lists of papers with others, including your comments about them, in a useable format Sharing lists of papers with others, including your comments about them, in a useable format Discovering other authors who commonly cite your own work, or the work of another Discovering other authors who commonly cite your own work, or the work of another ADASS XVII, London, September 26, 2007
