How Does KU Work?

Publishers + KU + Libraries = Open Access for Global Readers

Open access has its greatest value when it remains grounded in academic needs while also reaching those who can benefit from it more widely.

Content

Publishers submit titles and resources for pledging consideration.

Curation: KU Select Books Collection

Librarians worldwide are invited to vote on titles submitted for consideration

Curation: KU Partner Collections

Publishers provide thematic collections of titles and resources organized for pledging

Institutional Funding

Libraries, consortia, and research institutes pledge funds to support content.

Unlatching

If aggregate pledging is sufficient, content is published Open Access and made available to global readers.

We're delighted to be supporting the important work KU is providing in making scholarly works open access via collective funding models and consortium building. The University of Manchester has been a loyal supporter to KU for advancing Open Access right from the start and especially since it became part of the nonprofit Annual Reviews organization.
