  Statistics Philosophy

          ER&L 2010
    University of Notre Dame
Whatever shall we collect?
•   JR1 fulltext downloads (of course)
•   Impact factor
•   Eigenfactor
•   SFX Statistics (there’s a bunch)

        Can you make questionable numbers meaningful by
        adding even more questionable numbers?




                                                     ER&L 2010
Who has the time?
• I guess it’s my job
  » eJournal guy since 2000
  » Download JR1 every month (50 platforms)
     • Save as a whole bunch of spreadsheets, made
       accessible on an ugly website
     • Around 20% of my time (yes that’s way too much!)
  » There has to be a better way to do this, right?



                                           ER&L 2010
A better way
• Need a database for ease of access and
  reporting
  » Pay someone else
  » Build our own
• What is important to us?
  » Less time gathering stats
  » Find out what the numbers mean


                                     ER&L 2010
What do these numbers mean?
• Avoiding junk in, junk out
  » HTML vs PDF
     • Springer vs ScienceDirect
  » Outliers
     • Use spikes, fair or personal archiving
  » General bad data
     • Missing/incorrect issn
     • Duplicate data on same report


                                                ER&L 2010
What now?
• CORAL Usage Statistics
  » Less time, all logins in single location
     • Train someone else to gather reports
  » Download every quarter
     • How often do folks need new numbers anyway?
  » Better reporting
     • Collection managers can gather on their own
  » Filtering out questionable data (outliers)


                                              ER&L 2010
Statistics Philosophy
• Stats and nothing but the stats
  » JR1 only
• Interpretation
  » What do the numbers mean?
  » Can we clean them in any way?
• Functionality
  » Allow collection librarians greater access to
    reports

                                        ER&L 2010
