To be honest I'm not actually sure what can be done about this; the old links no longer have the same URLs, so I guess it'll simply take a while for old posts to receive enough hits at their new URLs to show up in the rankings again. But rather than let matters lie and hope for the best, it strikes me one thing I could do – or rather, you could do, if you feel so inclined – is to click on the masthead at the top of the blog or on some of the posts in the Existential Ennui Archive in the right-hand column. Doesn't matter which ones: pick a few favourites, maybe, or better still ones you haven't read before, and go and click the living bejeezus out of them. I have no idea if that will help, but I suppose at the very least it couldn't hurt.
This isn't mere vanity on my part, by the way (well, not entirely): the purpose, or perhaps point, of Existential Ennui, as has become gradually clearer over the past few years (to me as much as to anyone), is to be a repository of hopefully entertaining, amusing and diverting information about relatively obscure books and their publishing histories, and if no one can find that information, then the whole enterprise becomes essentially redundant. So, if you wouldn't mind: go, click. Click on the masthead, click on the posts... hell, click on Beautiful British Book Jacket Design of the 1950s and 1960s: that one's always worth another look. And thank you in advance for your time.
