APIs for Scholarly Research

Adam Matthew permits access to content licensed for the purposes of non-commercial text and data mining. Primary text mining is available through Adam Matthew's API, which includes full text but not images. Permission must be obtained.

Coherent Digital and Accessible Archives allows for data mining. Individuals must obtain permission.

APIs (Application Programming Interface) are tools that allow for computer-to-computer interaction. Elsevier Research Products APIs help researchers integrate Elsevier data into their work. Elsevier has APIs available for many products, including ScienceDirect, Scopus, Engineering Village, and Embase.

Can be used to retrieve content (page images, OCR, and in some cases whole volume packages), and metadata for HathiTrust Digital Library volumes.

IEEE Xplore® APIs provide access to metadata for more than 6 million documents available in the IEEE Xplore® Digital Library, including IEEE Journals, Conferences, Books, Courses, and Standards.
IEEE Xplore Metadata APIs can be used for: Content indexing / discovery services and Text and data mining (TDM).

Not a true API, but allows computational analysis and selection of JSTOR’s scholarly journal and primary resource collections. It includes tools for faceted searching and filtering, text analysis, topic modelling, data extraction, and visualization.

The New York Times API allows you to programmatically access New York Times data for use in your own applications (as long as it's for non-commercial purposes). NYT currently has ten public APIs: Archive, Article Search, Books, Community, Geographic, Most Popular, Semantic, Times Newswire, TimesTags, and Top Stories.

The OECD has application programming interfaces (APIs) that provide access to datasets in the catalogue of OECD databases. The APIs allow you to query the data in several ways, using parameters to specify your request so that you can create innovative software applications which use OECD datasets.
The APIs are available in JSON and XML formats.

The data in Overton is available in a machine readable format using our REST API, which sits in-between the database and the web application. Users must sign up for a free account.
API access is enabled by Overton- email lib-ejournals@virginia.edu to request access.

Robust set of APIs for metadata, images and articles from this scientific publisher of books and journals.

The REST API gives anyone free, programmatic access to the Unpaywall database.

The Web of Science API supports searching across the Web of Science to retrieve core item-level metadata. To get the full functionality of this API, you will need to submit for the Starter API key.

BioMed Central has a RESTful API for retrieving open access content published by BMC. Resources are represented in JSON and Prism Aggregate (PAM) formats.

A separate API and access to bulk OCR downloads are available for the 18+ million pages of digitized historical newspapers available in the Chronicling America database.

The digital collections available through LOC.gov may also be queried, or searched, using the Library of Congress Application Programming Interface (API).
