I'm quite sure that over the years I titled (at least) one of these pages 
  For instance, but considering that I've run two different checks for 
  the phrase and haven't found it in a title (though I've rather unavoidably used 
  it numerous times in my texts), perhaps I'm wrong. Perhaps it was a working 
  title that got changed in the end. It's a rather logical title for a page with 
  a list, especially if I've linked to Gilbert and Sullivan a number of times 
  already (though from my present checking it seems that I've only really done 
  that - about lists - only once, and that needed a bit 
  of updating). But enough of this. Do I have a list here?
  
  Not exactly. My repetitions are numerous - too numerous to list. But they do 
  follow a certain sort of pattern. If I reused a song title, for instance (there 
  it is again) I usually linked to where I did so the first time. In a similar 
  manner, if I wanted to "reuse" a comic that I'd posted in the past, 
  I preferred to link to it rather than repost it, usually explaining why the 
  context from which I now referred to was different. The same went for a particular 
  story that I chose to retell
  
  But it seems that twice instead of doing this I actually scanned the comic a 
  second time. In an examination of online communities 
  I post a comic that I reposted less than a year later within the context of 
  an examination of addiction to the internet. Chronologically, this was the first 
  time this repetition took place. The second repetition was slightly later, though 
  it referred to a comic that I'd used in the first year 
  of columns. The topic the second time around 
  was different enough (though since then a rather recurring one itself - the 
  idea that internet use has ceased to become something really worthy of our interest) 
  that I probably didn't even think to check whether I'd used the comic before, 
  though of course I had.
  
  Should this repetition distress me? My guess is that I'm the only reader who 
  may have noticed. Were a reader to ask him or herself "haven't I seen that 
  here before?", I suppose that it would have been only a minimally bothersome 
  question. And if that reader was to reread previous columns to find the source 
  of the repetition? Frankly, it might be an enjoyable experience. Leftovers can 
  often be very tasty when they're warmed-up again. I've even played with the 
  idea of a new column being no more than a link to an old one which I've reread 
  and enjoyed, and found still relevant. But though 
  it might be a cute trick, I'm fearful that it might become a habit, and then 
  I'd really be repeating myself.
