Scholarly Open Access (via Internet Archive)
Archive of a former blog focusing on a "critical analysis of scholary open-access publishing," including a list of predatory publishers. Considered the gold standard by many scholars concerned about predatory publishers, it was the main source of predatory publishers for several years. Others critiqued its inclusion criteria and a bias against journals outside of the highly developed world (U.S., EU, Canada, Australia, Japan). It was suddenly taken offline in January 2017.

Pay for publishing costs by charging article authors a publication fee (sometimes covered by institution or research sponsor)
Most major publishers have some fully open access titles.
Authors (or their supporting institution/sponsoring agency) pay a fee to have their article available without a fee on an otherwise subscription-only site.
Most commercial publishers have this option in some/most of their journals. For example, Elsevier allows this option in 1500 of its 3000 journals, while Wiley and SAGE allow it for most of their titles.
Example of mix of open-access articles within a subscription journal:
Free Access that is Technically not "Open Access" -
Free Articles: Some journals provide free access to selected articles within their subscription publications.
Free Issues: Many commercial publishers provide free access to single issues within an otherwise subscription-only publication, usually as a teaser to encourage new subscriptions.
Example: Asian Journal of Endoscopic Surgery (All articles from 2012, Volume 5, Issue 1 are free)
Some journals require a subscription for access to current content, but provide free access to older articles (often after 1-2 years).
Stem Cells (content older than 1 year is freely accessible, back to 1996)
Highwire Free (most titles provide free access to embargoed/archival content)
Wiley Free Backfiles (mostly medical titles)
