Non-Patent Literature Data Coverage

This article details the current scope of our non-patent literature (NPL) data coverage. We're continually expanding the coverage of our NPL search and we'll amend this article when new sources become available.

Current Data Coverage

Our database indexes millions of documents from a diverse range of scientific and technical sources.

You can find a breakdown of our data coverage by document type here: https://search.nlpatent.com/data-coverage?tab=npl

Note: These numbers are updated regularly as we ingest new data.

Full-Text vs. Abstract Indexing

Due to copyright restrictions, for most academic journal sources we're only able to display the abstracts and article metadata (authors, publication date, source, etc.) in the NLPatent platform.


Most results include a link to the original source where the full text can be accessed:
