Open Access: Publishing model that allows anyone to read the published material without the need for a subscription or other payment.

Closed Access: Traditional publishing model where the reader must pay or subscribe in order to access the published material.

Article Processing Charge (APC): A common feature of open access publishing models; the cost incurred by the author(s) from the publisher or journal required to publish within the open access model

OA Levels: There are multiple types of open access publishing models; there are several different kids indexed by WRDI:

Gold: Published content is immediately made fully available by the publisher on their own website under a creative commons or similar license

Green: Published content self-archived by the author(s) in an open access resource such as an institutional repository

Hybrid: Publisher or specific journal where each article can be published as either closed or open access, depending on author choices and APCs

Bronze: Material is free to read and access on publisher’s website, but lacks a definitive license; typically not available for reuse or remixing

Closed: Traditional publishing model where authors do not pay a fee but content is restricted behind a paywall or subscription service for the reader

Embargo: When a publisher holds the rights to a published material for a set period of time as set by the publication contract; after the embargo period ends, the published material is available as open access
