Below are the fields, definition, and how they are compiled.

-Collections

Total number of collections in Arctos with or without data

-Institutions

Total number of institutions in Arctos based on the administrative contact for a collection regardless of sponsorship status.

-CatalogedItems

This is the total number of catalog records that are in a collection. This includes encumbered records that are hidden from the public.

-Individuals

This is the sum of individuals based on the record attribute Individual Count for all records in a collection.

-UsedTaxa

This is the total number of taxon names (at any rank) associated with the total number of records in a collection.

-Localities

This is the total number of localities associated with the total number of records in a collection.

-GeoreferencedLocalities

This is the number of localities with geographic coordinates that is associated with a collection.

-CollectingEvents

This is the number of collecting events associated with records in a collection.

-SpecimenMedia

This is the total number of media objects in a collection.

-UsedPublications

This is the number of publications that cite catalog records in a collection. Many records may be cited in a single publication but that will only count as one (1) used publication.

-Citations

This is the number of times a catalog record in a collection is cited in publications uploaded to Arctos. If the same single catalog record is cited in multiple publications (e.g., in 17 publications), that counts as multiple citations (e.g., 17 citations).

-LoanedItems

This is the sum of all parts from a collection that are associated with any loan. This does not indicate anything about the number of catalog records those parts come from.

This is the number of catalog records with links to any GenBank records.

-SpecimenRelationships

This the number of specimens with an external relationship to another record (e.g., “host of” but not “self”)

-PartCount

This is the total number of parts in a collection regardless of what the part is as long as it is in collection or otherwise still part of the collection, thus excludes parts no longer available to the collection, specifically with the disposition of deaccessioned, discarded, missing, on loan, transfer of custody, used up, not applicable.

For example, in a single record where parts have the disposition of in collection such as foot (4), tissue (2), DNA (1), and skull (1) partcount will be the sum of the quantity of each part (e.g., partcount total is 8).
