Publisher object
Here are the fields in a publisher object. When you use the API to get a single publisher or lists of publishers, this is what's returned.
alternate_titles
alternate_titles
List: A list of alternate titles for this publisher.
cited_by_count
cited_by_count
Integer: The number of citations to works that are linked to this publisher through journals or other sources.
For example, if a publisher publishes 27 journals and those 27 journals have 3,050 works, this number is the sum of the cited_by_count values for all of those 3,050 works.
country_codes
country_codes
counts_by_year
counts_by_year
Years with zero citations and zero works have been removed so you will need to add those back in if you need them.
created_date
created_date
display_name
display_name
String: The primary name of the publisher.
hierarchy_level
hierarchy_level
Integer: The hierarchy level for this publisher. A publisher with hierarchy level 0 has no parent publishers. A hierarchy level 1 publisher has one parent above it, and so on.
id
id
String: The OpenAlex ID for this publisher.
ids
ids
Object: All the external identifiers that we know about for this publisher. IDs are expressed as URIs whenever possible. Possible ID types:
ror
String: this publisher's ROR ID
image_thumbnail_url

This is usually a hotlink to a wikimedia image. You can change the width=300
parameter in the URL if you want a different thumbnail size.

lineage
parent_publisher
parent_publisher
String: An OpenAlex ID linking to the direct parent of the publisher. This will be null if the publisher's hierarchy_level
is 0.
roles
roles
In many cases, a single organization does not fit neatly into one role. For example, Yale University is a single organization that is a research university, funds research studies, and publishes an academic journal. The roles
property links the OpenAlex entities together for a single organization, and includes counts for the works associated with each role.
sources_api_url
sources_api_url
String: An URL that will get you a list of all the sources published by this publisher.
We express this as an API URL (instead of just listing the sources themselves) because there might be thousands of sources linked to a publisher, and that's too many to fit here.
summary_stats
summary_stats
Object: Citation metrics for this publisher
While the h-index and the i-10 index are normally author-level metrics and the 2-year mean citedness is normally a journal-level metric, they can be calculated for any set of papers, so we include them for publishers.
updated_date
updated_date
works_count
works_count
Integer: The number of works published by this publisher.
