What are scholarly resource APIs ?

APIs, short for application programming interface, are tools used to share content and data between software applications.  APIs are used in a variety of contexts, but some examples include embedding content from one website into another, dynamically posting content from one application to display in another application, or extracting data from a database in a more programmatic way than a regular user interface might allow.  

Many scholarly publishers, databases, and products offer APIs to allow users with programming skills to more powerfully extract data to serve a variety of research purposes.  With an API, users might create programmatic searches of a citation database, extract statistical data, or dynamically query and post blog content.

Below is a list of commonly used scholarly resources at MIT that make their APIs available for use.  If you have programming skills and would like to use APIs in your research, use the table below to get an overview of some available APIs. 

If you have any questions or know of an API you would like to see include in this list, please contact Mark Clemente, Library Fellow for Scholarly Publishing and Licensing in the MIT Libraries (contact information at the bottom of this page).
