AncestryMagazine.com some time ago published a list of 300 "top" genealogy sources. The list is not a series of hotlinks to websites, it is a list of source categories (such as birth certificates, adoption papers, etc.).
The value of the list, whether you are an experienced researcher or not, is that you may see a source that has escaped your attention, or perhaps in one you have simply forgotten about.
You can peruse the list at: http://www.ancestrymagazine.com/lous-300/
