Double-dipping describes the situation where a journal charges an APC on top of its normal subscription fee if an author wishes to make their particular article OA. In effect, the institution is paying twice. (Hybrid OA)
A period of time defined by the publisher during which the author can not publish a self-archived open access copy of the publication in question. Embargo periods are typically from 6-36 months. The embargo period starts from the date of publication.

In addition repositories can hold 'grey literature' such as Theses, Discussion Papers, Datasets and other material for example Theseus.
The paper or article is published in a journal by a publisher, but a copy (usually the final draft) is made available OA in a repository. (Green OA)
