What Counts as Duplicate?

DeepGrooves identifies potential duplicates by:

  • Same artist and album title
  • Same Discogs release ID
  • Similar metadata patterns

Different pressings of the same album appear as duplicates—decide whether to keep both or consolidate.

Results show duplicate groups.

  • Catalog numbers
  • Condition grades
  • Purchase information
  • Notes

Context Menu

Right-click a duplicate entry for options:

  • Keep This One

  • Not a Duplicate

Troubleshooting

False positives

  • Different pressings are valid — A US and UK pressing aren't duplicates
  • Check catalog numbers — Same album, different number = different release

Before deleting

  • Review details carefully
  • Merge notes from both entries when consolidating
