Fixing mis-ordered fifles

title_order.rb

# Reports on and fixes mis-ordered titles.
# To run, download the raw output of the array of works with multiple titles. Open the file
# in a text editor and add "@@titles = " to the beginning of the line to set the array as
# class variable. Save the file as titles.rb and upload it to the temp directory of the server.
#
# From the Rails console, copy and paste in the code below. Run the report and fix the works.
# A possible sequence would be:
#
#   >  report = TitleOrder.new
#   >  report.misordered_titles
#   >  report.results.count
#   => 179
#   >  report.fix
#   >  report.misordered_titles
#   >  report.results.count
#   => 0
