Other Kinds of Authorities
Geographic places, materials (genre terms, form terms), and roles or occupations also use authorities; some of these are bundled into large authorities like the Library of Congress Name Authority File, which contains names and geographic places, or the Getty Vocabularies Art and Architecture Thesaurus, which has roles/occupations and terms that can be used as subjects or as genre/form terms. Others are specific to their domain, like Geonames (only geographic terms).
Anatomy of a genre term from an authority
Example
This term from the Getty Vocabularies can be used as a subject term or as a genre term depending on the item being described. We can see the preferred term and its position within the "Objects" section of the hierarchy.

How to Use Them
Geographic places, materials, and roles/occupations terms can be used similarly to subjects and names; they can be the subject of, mentioned in, or associated with a collections item. Materials can also be used to describe what the collections item is, or "isness." Roles/occupations can also be used to describe how individuals or groups are related to a collections item (ex. Joaquín García Icazbalceta collected the Relaciones Geográficas, so his role term could be "collector.")
Consider:
What are the most common locations or themes in the item?
What are the most common forms of the item?
Are there specific historical or cultural places, materials, or roles in the item?
NOTE: Some places may not be able to be recorded to ensure privacy or safety of the location. In these circumstances, refer to the resources in the Alternative Thesauri/Resources section or the Critical Metadata page in this wiki for more information.
Are there specific roles that connect your named subjects to the item?
Are there places, roles, or materials in the item that have historically been marginalized?
How are these places, roles, or materials described currently in their community or area of scholarship?
When choosing subject terms, consider:
Adding terms that most fully describe what the collections item is.
Adding terms that describe the most common and/or most important location(s) associated with the item.
Being specific and concise with term choice. Avoid narrow terms like "Newspapers--Mexico." Consider breaking compound terms apart and putting parts into their respective fields.
Highlighting histories that have been systematically marginalized (ex. using vernacular place names)
Using terms that are used by scholars and/or by members of that community. See the alternative thesauri below or the Critical Metadata page in this wiki for more information.
Adding only 1-2 terms to lessen visual load on the user.
Using the preferred term first, unless it is inappropriate for the context (ex. a variant term has the most updated form.)
Where to Find Them
The following list contains a set of the most common thesauri and controlled subject vocabularies, as well as a few that are used for specific material culture contexts. Best practice is to find terms in these larger resources first before looking for an alternative or creating one's own term.
Alternative Thesauri/Resources
If you can't find the term you need in the thesauri and controlled vocabularies above, or if the terms listed are not appropriate (outdated, not reflective of current scholarship, etc.), consider using some of the resources below. You can also create your own term (see the following guide.)
