   What's available is kept on Albert's Rubi website. Section headings of   
   the Timofeev and Hearn problems and file names of the Rubi development   
   testsuite are indicative of content. And the files can be downloaded   
   and searched for special functions of your interest.   
      
   These problem collections serve as a means of quantifying integrator   
   performance and identifying performance gaps (named suites), or as an   
   insurance against performance regression (Rubi development suite). I   
   have never felt the need for any sort of index.
