That is not to say that the blog solution is ideal, merely that it exists. My objection to the blog solution and potentially the UserVoice solution is that the priorities are by datatype and, at least for myself, the biggest problems come from books with unexpected glossaries at the end.

Some version of this request is needed ... I'm just not sure what will work best as long as placing a resource in the list prioritizes it for all it's indexed datatypes.
