The site allows you to search and view newspaper pages from 1880-1922 and find information about American newspapers published between 1690-present. To encourage a wide range of potential uses, they designed several different views of the data which are publicly visible and do not require an API key to use them.
This API allows you to:
- Search - the newspaper directory and digitized page contents using OpenSearch.
- Link - using stable URL pattern for titles, issues, editions, and pages.
- Linked Data - views of information about titles, batches, issues, and pages in RDF/XML.
- Aggregations - of items, like all the pages that make one issue, are related using OAI-ORE
