xISBN web service

• Takes an ISBN as input
• Returns list of ISBNs in associated work
• Significant processing
• Starts with control-number list of work-sets
• Uses ISBNs to pull work-sets together
• Allows fuzzy-matching on author/title
• Ends up with consistent clusters
• In general larger than those in control-number
  list

Summary

• Simpler when only work-level relationships are
  needed
• Even for work-level relationships, a number of
  different formats are useful
• Information needed for an interface gets much
  more complicated
