In my case the university reading lists were often unrealistically long - and were condemned as such by academics in another university where I subsequently did a postgraduate degree - so missed texts were understandable and normal. More interesting are the ones I set out to read, but which defeated my efforts to finish them. There were only two: Middlemarch and Sir Walter Scott's Heart of Midlothian. Surprisingly, I had no trouble at all in reading Gibbon's Decline and Fall, although only a limited number of volumes were set.
