In her comment on my 'Bookish' post, Kendra has identified something which had occurred to me too - which is that an awful lot of my gaps are American authors.
To some extent this is inevitable. British schools teach British authors, American schools teach American authors. However, my own experience suggests that a lot of schools could do a better job of saying "this isn't everything - go and seek out more". And an awful lot of British people could beneficially reflect that being able to see a foreign country from your doorstep (on a clear day, if you live in the right place) does not automatically bestow cosmopolitanism. Nor does visiting said foreign country to buy cheap wine in a British supermarket. Particularly if the cheap wine is Australian.
Meanwhile, I find myself protesting that my reading is wider than that one list suggests. A very unscientific survey of the books I can see from this chair without getting up takes me to Canada (Margaret Atwood, Douglas Coupland), Australia (Miles Franklin, A B Facey), South Africa (Barbara Trapido), India (Vikram Seth), Singapore (Hwee Hwee Tan) and the United States (Barbara Kingsolver, Armistead Maupin, Donna Tartt, Harper Lee, Mary McCarthy, Annie Proulx, Jeffrey Eugenides, Michael Cunningham, Joyce Carol Oates). I've excluded translations (which would add Japan, France, Turkey, Denmark, Sweden, Norway and Finland to the list). I've excluded authors writing about the past or countries other than their own. I've excluded all the books in other rooms, or which I've borrowed from libraries. But I'm only ever going to scratch the surface. No-one could read all the good books that have been written - but I can try to make sure that all the books I read are good.
And, apropos of school set texts, I would assume that someone educated in Britain would have had to read two plays by Shakespeare, probably a novel by Charles Dickens, a selection of War Poetry (mostly First World War) and either 'Lord of the Flies' or 'Animal Farm'. Contradictions invited. I would also love to know what the American equivalents might be.
By the way, Chris would like to it to be known that from the list that started all this off, he has read 'Brave New World' and 'Moby Dick', and is quite delighted to discover that there are books that he has read and I haven't. I point out that the missing word there is "yet".
