Open Access for Health Information: About Open Access

A research guide to locating Open Access resources for health information

What does "open access" mean?

Open Access literature is defined as being freely available online in a digital format. Traditional publishing models where a subscription to a journal is required to view research creates a barrier between information and the public. Open access (OA) allows research to be more easily shared between researchers and with the public.

Types of Open Access Publishing

Green - publishing in a non-OA journal but maintaining the rights to the works and archiving in an OA repository. This allows authors to meet the public access requirements that many research funding agencies have.

Gold - publishing directly in an OA journal, allowing more immediate access to articles than green publishing.

Hybrid - Some subscription/closed-access journals have an "open option" that makes an article free available to everyone.

There are two more distictions to keep in mind between OA resources: libre and gratis. These terms refer to the amount of licensing restrictions a work has:

Libre OA materials are free of most licensing and copyright restrictions on use of the work.

Gratis OA materials are free to use, but still have licensing and copyright restrictions.
