  • /publishers attribute filters
  • /publishers convenience filters

You can filter publishers with the filter parameter:

  • Get publishers that are hierarchy level 0 https://api.openalex.org/publishers?filter=hierarchy\_level:0

It's best to read about filters before trying these out. It will show you how to combine filters and build an AND, OR, or negation query

/publishers attribute filters

You can filter using these attributes of the Publisher entity object (click each one to view their documentation on the Publisher object page):

  • cited_by_count

  • country_codes

  • hierarchy_level

  • ids.openalex (alias: openalex)

  • ids.ror (alias: ror)

  • ids.wikidata (alias: wikidata)

  • lineage — Use this with a publisher ID to find that publisher and all of its children

  • parent_publisher

  • summary_stats.2yr_mean_citedness (accepts float, null, !null, can use range queries such as < >)

  • summary_stats.h_index (accepts integer, null, !null, can use range queries)

  • summary_stats.i10_index (accepts integer, null, !null, can use range queries)

  • works_count

/publishers convenience filters

These filters aren't attributes of the Publisher object, but they're included to address some common use cases:

continent

Value: a String with a valid continent filter

Returns: publishers that are located in the chosen continent.

  • Get publishers that are located in South America https://api.openalex.org/publishers?filter=continent:south_america

default.search

Value: a search string

This works the same as using the search parameter for Publishers.

display_name.search

Value: a search string

Returns: publishers with a display_name containing the given string; see the search page for details.

  • Get publishers with names containing "elsevier": https://api.openalex.org/publishers?filter=display_name.search:elsevier``

In most cases, you should use the search parameter instead of this filter because it uses a better search algorithm.
