OHEB and OGRK are available to non-translators.
Enhanced Resources are not.
There is no list that I am aware of. I did a quick look at resources that were available to download with a user that has no organization and there were over 1000 resources available.
There have been a number of requests over the years for a list of resources available within Paratext.
That could potentially be a feature-request, which could turn into an interactive table on the Paratext website.
The main issue is that not every organization has the same access to resources. I suppose that could be addressed in the table. And such a list could be an overwhelming amount of info.
All of the open-access resources should be the same though.
Thoughts?
