1. Search a digital library (e.g., nsdl.org) using different queries (e.g., "mars", "mars exploration", "Volcano World").
- If there are duplicate records, analyze and determine whether they are true duplicates.
- Also examine all records and compare these records describing the same resource.
2. Write a well-structured, brief report about your findings.
- Attach the records that you corrected or enhanced, and
mark your corrections or additions on the original records.
