As a firm believer in the wider dissemination of knowledge, IntechOpen supports the OAI Metadata Harvesting Protocol (OAI-PMH Version 2.0).

The OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting) is a protocol used to collect metadata descriptions and to enable other archives to access our database. The Protocol has been developed by the Open Archives Initiative, thus setting interoperability standards in order to ease and promote the broader and more efficient dissemination of content within the scientific community.

We have implemented the Protocol which increases the number of readers of our publications. All material is more widely accessible with resulting benefits for scholars, researchers, students, libraries, universities and other academic institutions. Through this means of exposing metadata, IntechOpen enables citation indexes, scientific search engines, scholarly databases, and scientific literature collections to gather the metadata from our repository and make our publications available to a broader academic audience.

As a Data Provider, metadata for published book chapters and journal articles is available via our interface at the base URL: http://www.intechopen.com/oai/?.

Some databases, repositories and search engines that provide services based on metadata harvested using the OAI metadata harvesting protocol are:

BASE - Bielefeld Academic Search Engine

One of the world's most powerful search engines, mostly for academic Open Access web resources.

WorldCat - OCLC

A search engine for online catalogs of publications from all over the world.
