Biblio Commons is a social virtual library that helps users to integrate Biblio Commons data into a website and other mobile applications. The core of Biblio Commons is to promote discovery, searching and borrowing in a more integrated manner. This API is particularly useful for developers working in libraries and are interested to replace the traditional functionality of a library into a set of interactive experiences that users might find more convenient. The API is about the integration of data collection in a social and interactive place. Some of the features of the API include record synchronization, easy configuration and uniform integration. The Biblio Commons API supports REST features. Right now developers can send HTTPS requests and receive JSON objects. Developers can find a complete list of URL structure, authentication, and resources.
