What is Open Access exactly?
By “open access” to [peer-reviewed research literature], we
mean its free availability on the public internet, permitting any
users to read, download, copy, distribute, print, search, or link to
the full texts of these articles, crawl them for indexing, pass them
as data to software, or use them for any other lawful purpose,
without financial, legal, or technical barriers other than those
inseparable from gaining access to the internet itself.

COAR: About harvesting and aggregations …
“Each individual repository is of limited value for research: the real
power of Open Access lies in the possibility of connecting and tying
together repositories, which is why we need interoperability. In
order to create a seamless layer of content through connected
repositories from around the world, Open Access relies on
interoperability, the ability for systems to communicate with each
other and pass information back and forth in a usable format.
Interoperability allows us to exploit today's computational power so
that we can aggregate, data mine, create new tools and services,
and generate new knowledge from repository content.’’

The document discusses the CORE system, which aggregates open access content from repositories worldwide. It provides statistics on CORE, including that it indexes over 16 million records from 500+ repositories. It also describes several applications and services that CORE provides, such as a portal, mobile access, and tools for analytics and policy compliance. Finally, it discusses CORE's collaborations with other projects around aggregating and analyzing open access content on a large scale.

Editor's Notes
- #27 In this paper, we use the term institutional repositories (which are the main interest of the Open Repositories conference), to refer also to subject-based repositories or archives or systems for depositing research outputs used by open access publishers. As a result, the conclusions of this paper and recommendations are equally valid for both the green (self-archiving) and gold (OA publishing) routes to OA.
