April’s “Third Wednesday Free-for-All” will be dedicated (nominally and initially, at least) to those labels so dear to the hearts of the buyers at Barnes & Noble, without which they would have no idea what shelves to put books on. Or, if you’re a pedant, “what shelves in which to put books.” Please feel free to comment and reply to this post with your thoughts and experiences so we’ll have something to trample underfoot on the third Wednesday in April.
