Open Access Week: OA Types

So far, I have been referring to three different categories of Open Access. To review:

Green Open Access: Authors self-archive or deposit a pre- or postprint of an article in a repository of some kind or on an author web site.

Gold Open Access: Authors publish articles in a fully open access journal, often upon payment of a publication fee or "article processing charge" (APC).

Hybrid Open Access: Authors publish OA articles in a traditional subscription-based journal upon payment of an APC.

However, new categories continue to crop up in the literature. Several that are more relevant for my purposes are as follows:

Diamond Open Access: Authors publish articles in a fully open access journal that does not require payment of a fee or APC.

Bronze Open Access: Authors publish articles in an online journal that offers free-to-read articles but does not include a license that specifies reuse or other rights associated with open access. This type of journal does not meet the criteria for inclusion in the DOAJ. Also referred to as "Gratis OA."

Temporary Open Access: Traditional publishers often make certain articles freely available to read for a temporary period of time. Usually, there are no additional permissions associated with this access.

In the end, Open Access is a spectrum with many variations, as can be seen on this chart.
