Astronomy Resources by Marcus P. Zillman.
From the post:
Astronomy Resources (AstronomyResources.info) is a Subject Tracer™ Information Blog developed and created by the Virtual Private Library™. It is designed to bring together the latest resources and sources on an ongoing basis from the Internet for astronomical resources which are listed below….
With some caveats, this may be of interest.
First, the level of content is uneven. It ranges from professional surveys (suitable for topic map explorations) to more primary/secondary education type materials. Nothing against the latter but the mix is rather jarring.
Second, I didn’t test every link but for example AstroGrid is a link to a project that was completed two years ago (2010).
Just in case you stumble across any of the “white papers” at http://www.whitepapers.us/, also by Marcus P. Zillman, do verify resources before citing them to others.
