The below lists have items that have not been filtered out of the GreenGlass Universe.
Records for which GreenGlass has assigned an OCLC number
As part of our normalization routine, GreenGlass uses LCCNs and title similarity logic to identify matching WorldCat™ records. These are records for which the library’s record does not contain an OCLC number. In exported lists, the GreenGlass assigned OCLC numbers can be found in the column labeled WorldCat OCLC Number.
Records for which your library's holding is not set in WorldCat™
These records were included in your data extract so we assume local ownership. However, at the time of our WorldCat™ look-up, your library’s holding was not set or was not set on the exact edition.
Multi-edition titles
This list contains titles for which your library holds multiple editions. Whenever two or more titles with different OCLC numbers are found to share a common OCLC Work ID, they are included.
Items are sorted by OCLC Work ID with more recent editions showing first. The OCLC Work ID links related editions of the same work in WorldCat. Related editions can include new, revised, expanded or sequential editions, alternate US or UK editions, ebook editions, large print editions, or reprints.
Every OCLC Work ID associated with multiple items in your collection will appear in this list if there are multiple OCLC numbers represented in the set. This will exclude simple duplicates and multi-volume sets where all the volumes are part of the same edition.
When there are multiple OCLC numbers associated with a single OCLC Work ID, all associated items will appear in this list.
Note: This list includes your library's out-of-scope items.

Possible duplicates
GreenGlass flags an item as a possible duplicate when there is more than one item associated with a single OCLC number and:
- Any of those items has a null enumeration;
- Two or more of the items share the same enumeration; OR
- Two or more of the items share the same volume number but not the same copy number. Note that this list includes your library's out-of-scope items.
When these requirements are met, GreenGlass displays the entire set of items that share the OCLC number. Each item in the set has an assigned possible-duplicate flag. Only items flagged with a YES are suspected duplicates. The others are included to provide context.
- Duplicates are flagged across all locations.
Click Export Results to export a complete list of possible duplicates, sorted by OCLC number.
Additional areas to use the Possible Duplicates feature:
- Possible Duplicates are also incorporated into the Key Metrics at the bottom of the Overview page and also include all duplicate items plus the items that share an OCN. The Possible Duplicates key metric makes it possible for you to compare your library’s collection with the others in this respect. Refer to Overview for more information.
- For libraries with very large collections, the complete Possible Duplicates list is too large to be convenient. Use the Possible Duplicates search parameter in the GreenGlass Query Builder to include or exclude possible duplicates in the query results. See Query Builder for more information.
