It used to be in the web "my last seminary" / "summer seminary site" with a lot of links for topics on philosophical and theological issues. Does somebody know to where it migrated or mirrors?
Fortunately, this was a temporary problem which is now solved
The site you are looking for has used two domain names over the last 15 years or so: lastseminary.com and apollos.ws. At present, either of these names, with or without a prepended www, should resolve to www.lastseminary.com where the content is.
It appears there was an error redirecting from one url to another. The primary site has been apollos.ws for the last several years, and a lot of the content should be available on archive.org if you ever have trouble finding it on lastseminary in the future. Most of my original answer is no longer valid. If you are interested in the technical details, it should still be in the edit history.
A description on the site (as originally found at archive.org):
What is Apollos.ws
Apollos.ws is a resource for Christian academics. We organize audio, video, books, and articles related to Philosophy of Religion, Apologetics, and Biblical Studies. This site is an ideal research tool for graduate and post-graduate students.
The site is quite limited in describing and 'selling' itself. As an example, the easiest way I know to find their 'about us' page is to search for it. If you include the quotes in the search, you will get only one result. In my opinion it is a very useful reference site.
