In addition to commercial publishers, a number of open access publishers have been established in the last twenty years and the open access movement continues to gather momentum. The page provides a listing of open access resources.
One of the resources listed is the Directory of Open Access Journals. This is the gold standard for open access journals. If you find an open access journal which isn't listed, be careful, as it may be of dubious quality, and you should evaluate its quality by using the CRAAP test or SIFTing.

The list is problematic in that it reflects the bias of its creator and should be considered advisory and not authoritative.
