  ::: You are right, one sentance isn't enough to do the subject justice, please ammend as you see fit. At some point in the future,the article should at least contain a paragraph, if not a section, covering the dust jacket artwork changes, and the inclusion of the b&w; illustrations to the UK and US editions. I do think that print issues and dust-jacket / binding / typography /paper weights should indeed be covered in every book article, where these things have been discussed in the literature. A comparison with something like Harry Potter - which had multiple covers ('adult'/'kiddy'), 7-colour offset with gold spot printed in china (I'm guessing) - shows that process is clearly indicative of time/place - not that the article needs to make that comparison, but the reader should be able to obtain a materials, processes and design understanding of a book from a Wikipedia article. Other than on a general principle, specifically with The Hobbit, the work is 'all of a piece' being a culmination of Tolkien's creative endeavours, and should reflect that.
