Recently, I'd noticed yet another question on something along the lines of "I need a book recommended to me", and I thought "Oh, I'll go search through the listing of questions with 'book' in the title..." and subsequently stumbled upon the elusive books tag, and was surprised at the number of closed questions in my search.
Now, the two of them contradict each other a bit - the search reveals that a good 65%+ of the questions (through search) are closed, but only about a third of the [books]-tagged questions are closed...
What are our policies on these questions?
From what I know, they should be closed/deleted (though, under what flag? should we try to find duplicates if possible?). Should they instead be left alone, under some kind of conditions? (what would these be, in that case?)
