Prepare your data (Fundamentals)

Discover how to evaluate your library's records and files for potential problems before you send your files.

 Note: If you are a WMS library or using full WorldShare Collection Manager, please see Prepare your data.

 Caution: Currently when the system identifies duplicate records or multiple matches in your submitted data sync file, the file will be rerun in an attempt to resolve the issue. Multiple reports and files may be generated for each retry.
