Filter sources

You can filter sources with the filter parameter:
Get sources that have an ISSN
https://api.openalex.org/sources?filter=has_issn:true​
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
/sources attribute filters
You can filter using these attributes of the Source entity object (click each one to view their documentation on the Source object page):
​apc_prices.currency​
​apc_prices.price​
​apc_usd​
​cited_by_count​
​country_code​
​host_organization (alias: host_organization.id)
​host_organization_lineage — Use this with a publisher ID to find works from that publisher and all of its children.
​ids.openalex (alias: openalex)
​is_in_doaj​
​is_oa​
​issn​
​publisher — Requires exact match. Use the host_organization_lineage filter instead if you want to find works from a publisher and all of its children.
​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)
​type​
​works_count​
​x_concepts.id (alias: concepts.id or concept.id)
Want to filter by host_organization.display_name? This is a two-step process:
1.Find the host organization's ID by searching by display_name in Publishers or Institutions, depending on which type you are looking for.
2.Filter works by host_organization.id.
To learn more about why we do it this way, see here.​
/sources convenience filters
These filters aren't attributes of the Source object, but they're included to address some common use cases:
continent
Value: a String with a valid continent filter​
Returns: sources that are associated with the chosen continent.
Get sources that are associated with Asia
https://api.openalex.org/sources?filter=continent:asia​
default.search
Value: a search string
This works the same as using the search parameter for Sources.
display_name.search
Value: a search string
Returns: sources with a display_name containing the given string; see the search page for details.
Get sources with names containing "Neurology":
https://api.openalex.org/sources?filter=display_name.search:Neurology``
In most cases, you should use the search parameter instead of this filter because it uses a better search algorithm.
has_issn
Value: a Boolean (true or false)
Returns: sources that have or lack an ISSN, depending on the given value.
Get sources without ISSNs:
https://api.openalex.org/sources?filter=has_issn:false``
is_global_south
Value: a Boolean (true or false)
Returns: sources that are associated with the Global South.
Get sources that are located in the Global South
https://api.openalex.org/sources?filter=is\_global\_south:true​
