| Location Name | A natural language translation of the location code. Often used in the OPAC display. |

Same and Any Edition Holdings Tallies
In GreenGlass, there are two ways to estimate the extent to which titles in your collection are widely or scarcely held by other libraries:
- Same Edition Holdings Tallies: represent the number of libraries that have a holding set in WorldCat on the same OCLC number as yours, or, on an OCLC record that has been merged with yours.
- Any Edition Holdings Tallies: represent the number of libraries that have a holding set on the same or related edition of the work as established by OCLC's implementation of work families.
In Exported Item Lists, Same Edition tallies and Any Edition tallies are delivered in separate columns.
Note: Any Edition holdings tallies represent the number of libraries that have a holding set on the same or related edition of the work. Same and Any Edition tallies will match if there are no other editions of this work. If they don't match, Any edition tallies will always be bigger.
Additional views of Same and Any Edition Holdings Tallies:
- In Collection, Visualize, Same edition and Any edition tallies appear when the Comparator Libraries distribution type is selected.
- In the GreenGlass Item Lists, Same edition tallies precede the slash and Any Edition tallies follow the slash.
- In Query Builder, choose to set WorldCat overlap thresholds on Same or Any edition tallies via the radio buttons. Example use cases include:
- Lists of weeding candidates
- Use Same Edition thresholds to return smaller lists of weeding candidates.
- Lists of scarcely held titles
- Use Any Edition thresholds to avoid identifying too many titles that are not rare.
- Lists of weeding candidates
