“Ezra Klein”:http://voices.washingtonpost.com/ezra-klein/2010/02/against_books_–_sort_of.html
bq. It is true that for the best books, there is no substitute for a book. I do not want to read Robert Caro’s blog posts if they will delay his final volume on Lyndon Johnson by so much as an hour. But for many books, a few blog posts, or an article, would work just fine, and the reader would save a lot of time in the process. And time has value.
I think you can push this argument further. I would estimate that about 80% of the non-academic non-fiction books that I do not find a complete waste of time (i.e. good books in politics, economics etc – I can’t speak to genres that I don’t know) are at least twice as long as they should be. They make an interesting point, and then they make it again, and again, padding it out with some quasi-relevant examples, and tacking on a conclusion about What It All Means which the author clearly doesn’t believe herself. The length of the average book reflects the economics of the print trade and educated guesses as to what book-buyers will actually pay for, much more than it does the actual intellectual content of the book itself. Length may also, of course, reflect some practical judgments concerning the book as a display object (I seem to remember Tyler Cowen somewhere suggesting that only a relatively small percentage of books bought are actually _read_ ). Books which are, for example, extended versions of articles written for _The Atlantic_, _The Public Interest_ or what have you are _especially likely_ to be over-long for their topic – I don’t remember ever reading one of these books and feeling that I got substantial insights which were unavailable in the original article (in some cases it might have been useful to have a better sourced and slightly better fleshed out version of the original piece available somewhere, perhaps half the length again of the original piece, but there doesn’t appear to be a market for that).
All this may be changing as we move towards an electronic book publishing system. The economics of electronic text production are not the same as the economics of book production (as best as I understand either), and there aren’t the same pressures towards standardization of length. I suspect that people who would feel cheated if they paid ‘book’ price for a long essay (say around 20,000 words or so) will feel less so if they buy an electronic version. Ideally, we will end up in a world where people won’t feel obliged to pad out what are really essays to book length in order to get published and compensated. If I’m right, we will see a lot more essay-length publications than we used to. I suspect too that the effects will be non-symmetrical – that is that we will see an explosion in the number of very short books/essays, which will be somewhat cheaper than traditional books, but not very cheap, a moderate decrease in the number of ‘standard’ (say, 60,000-90,000 word length) books, and stability or decrease in the number of long books (books with 100,000+ words). Long books still cost a lot of money to edit. I also suspect that we will see traditional printed books become (a) more expensive, and (b) more beautiful – their main value will be as display items rather than use items. Of course, I have no direct experience of the publishing industry (except as author) and know that several of our commenters know more, and have strong opinions, so look forward to being corrected on any or all of the above …
