Fifty works of English Literature we could do without(Potentially relevant link)
A book by Brigid Brophy, Michael Levey, and Charles Osborne.
I haven't read it, but I've read the E2 node a few times. Summary: here're fifty books that have been parodied and rehashed and made tribute to so many times that we recognise any references to them without needing to read them.
Is it true? I don't know. /Hamlet/ is on the list, and you don't need to have read that to be very familiar with it, but I don't recognise many of the titles on the list. I guess its about their being alternate works to which to redirect the references, not there being common knowledge about them.
That's all. I just felt like posting something here, and that's what I came up with. Sorry.
